Different scene depending on level completion time remaining?

Hi guys,

I'm trying to incorporate a function where a player must reach an area within a particular time limit. I've got my timer script set up so when it reaches zero, a 'gameover' scene is loaded:

 var startTime = 90.0;
 
 var timeLeft : int;
 
 
 function Update () {
     
     //Time left
     
     timeLeft = startTime - Time.time;
     timeLeft = Mathf.Max (0, timeLeft);
     guiText.text = FormatTime (timeLeft);
     
     if (timeLeft == 0) {
         print ("Time is up!");
         Application.LoadLevel("gameover");
     }
     }

Now I'm trying to figure out how i can add a function so when the 'player' collides with the 'portal' with say, 20 seconds left to spare, a scene indicating that they'd won a 'gold medal' would load up. If they instead happened to finish with 10 seconds left to spare, then a different scene would load up indicating that they had won a 'silver medal' etc. Overall, I'm aiming to produce three different end-of-level scenes (Gold, Silver, Bronze).

I have a script attached to the 'portal' gameobject which currently identifies if the 'player' collides with it, to then apply a Application.LoadLevel function. Of course, with this new function I am trying to implement, I'm assuming i would need to pass some kind of if statement through? This is the script after various attempts of getting the newly proposed function to work:

    var timeLeft : int;
 
 function OnCollisionEnter (theCollision : Collision) {
     
     if(theCollision.gameObject.name == "player"){
         (timeLeft > 20) {
             print ("Gold!");
             Application.LoadLevel("gold-medal-scene");
         }
     }
     }
 

  //if (timeLeft > 10) {
             //print ("Silver!");
             //Application.LoadLevel("silver-medal-scene");

The commented out section is what I am assuming is the way I would get the function to work, but the problem i have is that I already have an if statement applied to the OnCollisionEnter script to identify the collection detection. :/

So I'm writing to ask for your advice and help as to how I could pass this proposed function within the script that I have. Any guidance would be greatly appreciated!
