Well, if by any chance you are using Apache as your webserver, you could always use the Apache::Session module, which will happily generate unique numbers for you.

If you choose to make use of Apache::Session for this purpose, you would always have the option down the road to make use of the session support it provides -- allowing you to store data in the server across requests. Good luck!
