Your function override has to match exactly for Unity to recognize it. You are using BoxCollider2D instead of Collider2D. Use this instead:

 function OnTriggerEnter2D(coll: Collider2D)

Also make sure there is a rigidbody attached to the gameObject and that the collider has the Is Trigger box checked. You can add Debug.Log() statements inside the function (outside of the "if"s) to make sure the function is getting called.

I modified the script in this way. Do you have any Suggested for addattarlo a boxcollider2D?

pragma strict

 static var GRENADE_AMMO = 0;
 static var temp : int = 5;
 var Sound : AudioClip;
 
 function OnControllerColliderHit(hit : ControllerColliderHit)  
 { 
   if(hit.gameObject.tag == "crateGrenades")
   {
        Destroy(hit.gameObject);
       
       gameObject.audio.PlayOneShot(Sound);
                                    
        GRENADE_AMMO += 4;
        
        print("YOU NOW HAVE "+ GRENADE_AMMO +" GRENADES");
        GameObject.Find("g_Count").guiText.text = ""+GRENADE_AMMO;
           
    }    
   }

Try this:

 #pragma strict
      static var GRENADE_AMMO = 0;
      static var temp : int = 5;
      var Sound : AudioClip;
      
      function OnTriggerEnter2D(hit: Collider2D)  
      { 
        if(hit.gameObject.tag == "crateGrenades")
        {       
            gameObject.audio.PlayOneShot(Sound);
                                         
             GRENADE_AMMO += 4;
             
             print("YOU NOW HAVE "+ GRENADE_AMMO +" GRENADES");
             GameObject.Find("g_Count").guiText.text = ""+GRENADE_AMMO;
     
             Destroy(hit.gameObject);
                
         }    
        }
