UnityEditor namespace is invalid

I have already looked at many of the possible solutions here: http://answers.unity3d.com/questions/316805/unityeditor-namespace-not-found.html

The problem is that it doesn't quite solve the issue I'm experiencing.

What I am developing is a tool for animators who are not programmers and do not spend much time learning the subtle nuances of Unity. This tool allows them to create an event trigger in their game that can attach a specified script to an object and run it all without needing to understand Unity. I have had the program work so beautifully by allowing the user to select a script in an editor-window and have it stored in a game script like so:

 public UnityEditor.MonoScript script = null;

The problem is that this cannot exist within the assets folder when I try to build (or rather, when the animator builds their demo-reel). I have tried SO MANY workarounds. This is the current workaround that gets the closest to working...

I have the user write the name of the script they want to be attached, it is stored as a string as such:

 public string script = null;

Then later on I try to find and attach the script using this function:

 public void ScriptAtTime(ArrayList scripts, GameObject obj, float oldTime, float newTime) {
     // iterate thorugh all the scripts
     foreach (ScriptKey scriptKey in scripts) {
         // if the ScriptKey is keyed for this time then assign and run it
         if (scriptKey.time >= oldTime && scriptKey.time < newTime) {
             // only attach the script if it exists
             if (scriptKey.value != null) {
                 
                 // find the script
                 Component theScript = null;
                 
                 string debugString = "Found " + Resources.FindObjectsOfTypeAll<MonoBehaviour>().Length + " scripts. Names are: ";
                 bool first = true;
                 foreach (Component comp in Resources.FindObjectsOfTypeAll<MonoBehaviour>()) {
                     if (!first) {
                         first = false;
                     }
                     else {
                         debugString += ", ";
                     }
                     debugString += comp.name;
                 }
                 Debug.Log(debugString);
 
                 foreach (MonoBehaviour comp in Resources.FindObjectsOfTypeAll<MonoBehaviour>()) {
                     if (comp.name.Equals(scriptKey.value)) {
                         theScript = comp;
                     }
                 }
                 
                 // attach the script (if it was found)
                 if (theScript != null) {
                     obj.AddComponent(theScript.GetType());
                 }
             }
         }
     }
 }

The problem I am having is that it doesn't find scripts within the Assets folder or any of its sub-directories. Instead, it finds scene objects which have scripts attached to them. This is obviously not what I want. How can I find a script in the resources using its name and attach it to an object. Keep in mind that simply using the string itself

 obj.AddComponent("myScript");

As described here http://docs.unity3d.com/ScriptReference/GameObject.AddComponent.html is no longer valid. That would have been the perfect way to do this!

So I ask again, how can I find a script by its name in the resources and attach it to an object?
