What's your version of MySQL? A change was made in 3.23.56 to intialize
the randomizer better.

I want to thank everyone for helping, and it's now working somewhat
the way I want it. Instead of relying on rand() by itself I'm passing
it a seed composed of a number generated by ruby's rand() and the
current system time in seconds, and that's giving me some comfortably
random results.
