two different collider in one script

hi everyone i have a problem in this script. i making a time system script with two different collider one is for the finish line the other is for pause the time. how do i put two different colliders in one script?

pause time:

function OnCollision (hit : Collider) {

Debug.Log("collision");

if(hit.tag == "clock") {

 //Race is finished
 
 isPaused = true;

}

}

finishline:

function OnTriggerEnter(other : Collider)

{

//var otherScript : ScoreScript = GetComponent(ScoreScript);

 // If you have no other triggers, 
 // you can ignore the tag check.

 if (!enabled || other.tag != "finishline") 
 
     return;

 if (++score >= goal) 
     Win();

}
