Could you recover ordering by the producer sticking a sequence number 
into the message? That should work as long as all the produced messages 
end up in the same queue.

Also note that rabbit sets the 'redelivered' flag on deliveries that 
have been sent to a consumer for the second and subsequent times. This 
too helps in recovering order.
