Help with sorting highscore - rsort()

Hi all you beautiful people

I'm making a Flashgame with a php highscore.
In my game I have a timer and I want the highscore to show me the lowest time.
But the code is created to show the best score.
I think I have to do something with the "rsort" or something.

Can anybody help me with this?

It works as it is, but the highest time is sortet to the top not the bottom.

If you help me I will include your name in the credits of the game.

Start the game and click on the button named "Highscore" to test the Highscore.

The game is far from be finished...
