The simplest way to do this is:
#declare lower_bound = something;
#declare upper_bound = somethingelse;

#declare MySeed = seed(2531); // or some other number, big and prime is nice

object { whatever
              translate lower_bound + rand(MySeed)*(upper_bound - lower_bound) }

// end
something and something else can be vectors, but they will distribute within a
straight line, so you will have to do this in triplicate for three different
vectors to fill space.
