There are a few ways you could go about this. If you have a consistent naming convention, you could split the string after the "ball" and just read the number.

  //given balls' names are "ball1", "ball2" and so fourth.
  //ballCollider is the collider passed into OnTriggerEnter
  var number : String = ballCollider.gameObject.name;
  number = number.Remove(0, 4);
  guiText.text = number;
 
  //if you want to parse the number...
  var numberInt : int = Int32.Parse(number);
  //now you have an integer representation of it.

or you could add a script to each ball that stores a value:

 //BallScript.js
  var value : int;

and then the trigger:

  OnTriggerEnter (ballCollider : Collider) {
       guiText.text = ballCollider.GetComponent.<BallScript>().value.ToString();
  }

i am adding script to each ball and i am using the value i get from collision for score calculation when collision happens the i get a value from the ball due to ball get destroying as script is inside the ball the script is also get destroying along with the ball so i cannot able to access the numeric value that i get according to the ball which collided for further score calculation

Then put them in an array when there destroyed:

  var list = new int[10];
  
  OnTriggerEnter () {
     var number = .......
     list[number -1] = number;
  }
