To pause use:

this is C#

  if (Input.GetKeyDown("p")){
                 Time.timeScale =0;
                 }

For unpause use Time.timeScale = 1; This has many interesting effect, for example if you use 0.5 instead of 1 you can slow down time.

You can also use a static boolean ^^

You could need a menu that uses time to make some effects.. (for example a pause menu with a bar that goes up/down smoothly)

 public static class Utils {
     public static bool Pause = false;
 }
 
 // ...
 
 public class PausableClass {
     public void Update() {
         if(!Utils.Pause) {
             // Do some stuff
         }
     }
 }

There's many cool other ways to do so : for example, Broadcast some messages such as "OnPause" and "OnResume"

http://docs.unity3d.com/Documentation/ScriptReference/GameObject.BroadcastMessage.html

The time scale should be used to slow/accelerate time in order to make some cool effects. Not to pause the game, because its effect is global. You can also use it for Debug purposes..

//That script works for me C#

public bool CanPause;

 void Start () {
     CanPause = true;
 }
 void Update () {
     if (Input.GetKeyDown (KeyCode.Escape)) {
         if(CanPause)
         {
             Debug.Log("pause");
             Time.timeScale=0;
             CanPause = false;
         }
         else
         {
             Time.timeScale=1;
             CanPause=true;
         }
     }
 }

Nope. Time scale doesn't really pauses your game. In a game you could use the time scale for other things. You could also need the time scale to be at 1 in your pause menu, so I think that's a bad idea :) A simple boolean must do the trick ^^
