This code works fine on a machine that I use with Free BSD and PHP v3.05.
If you read the change log, you will see that rand() was improved for some
machines in PHP 3.06. You might like to see if upgrading solves your
problem.
Your code has one problem though, you are getting a random index between 0
and $count. You want one between 0 and $count-1
