Doug,
     I have the beast you are looking for.  As far as getting them new 
and in quanity, good luck!  Your best bet would be to visit your local 
pinball house and find out who fixes the old mechanical pinballs, as they 
are about the only thing that still uses those sorts of parts.  Expect to 
pay around $25 for a used rotery realy.
     If I remember right the realy I have has 20 or so sets of DP 
contacts, and increments one contact set per pulse.  A bit of TTL should 
get you a thing where you can apply a binary number and have it step to 
the right set of contacts.
     If you think it will do what you want I will send it to you for $15 
including shipping.  It just is not worth my time to box it up and truck 
on over to UPS for less.
