Click object and it will randomly change its position + add score

Hi we have this code for S_Click.js

 private var button: GameObject;
 
 private var ScoresText: GameObject;
 
 
 
 function Start(){
 
 
 
 ScoresText= GameObject.FindGameObjectWithTag("Player") ;
 
 button= GameObject.FindGameObjectWithTag("Finish") ;
 
 
 
 
 
 }
 
 
 
 function Update()
 
 {
 
     if(Input.GetMouseButtonDown(0))
 
     {
 
         var hit : RaycastHit;
 
         var ray : Ray =Camera.main.ScreenPointToRay(Input.mousePosition);
 
         
 
         if(Physics.Raycast(ray,hit))
 
         {
 
             ScoresText.GetComponent(S_Score).score+=1;
 
             if(hit.transform.tag == "Finish")
 
             {
 
                 var position =Vector3(Random.Range(-6,6),Random.Range(-6,6),0);
 
                 
 
                 //Destroy(this.gameObject);
 
                 hit.transform.position=position;
 
                 
 
             }
 
         }
 
     }
 
 }

and then for the S_Score.js

 var ScoresText: TextMesh;
 
 var score=0;
 
 function Update(){
 
     ScoresText.text="$ :      " + score.ToString();
 
     if (score == 15){
 
     print ("ok");
 
     }
 
     }

what could be so wrong? when I click the object, it should add 1 to the score... it's already changing its position.

thanks iff you help me!
