How long 'tween now and then?
On Win2k you can schedule things using the scheduler (the GUI version of AT.EXE, which for some dumb reason, is not the same thing.) Open Explorer to your computer and you should see a folder called "Scheduled Tasks" at the same level as the drives. There you can click "add task" and be greated by the schedule wizard. You can browse to your script from there and specify the username to run it under.
I know its not very Perl-ish, but its the most straight forward MS-ish way to do it.
