Don't use rand() as the name. Now that ORM::load_types() is gone, it

won't get coerced to a string, and then we wind up comparing:

  12345 != 12345-12321

In the old approach, they'd both be strings so they'd be inequal.  But
in the new approach the first value is an integer (sinced it came from
rand()) so the second value is typecast to an integer which drops
everything after the - sign so they appear equal.
