How to make the 'lowest score' the 'hiscore'?

First time posting here, so i'll cut to the chase.

The game im making (only small) is time based, so the faster you complete it the better. How would i make it so the lowest time goes at the top of the hiscore?

Also, is there a way to set a timer (counter) to display milliseconds. Currently i'm using every 1/100 seconds add 1 to counter. I would like it to display 1/1000 seconds.

Thanks.

Try the time/date object, it's in one of the extension packs ------->

I don't know how to answer your first question, though. You might have to make a manual hiscore.

Alright thanks.
