traceroute multipath order

Interesting question... A L3 device with equal cost paths to destination.  Both next hops are equal distance in terms of AD and metric (think shared segment with 3 devices).  Traceroute will show both next hops when in the reply.  Now, how does the router determine the first probe to send to?  And how do you change this behavior? 

For example, traceroute will send probe to both and (equal cost next hops).  Now, was the first probe sent simply because its lower?  How do you change this behavior such that will be sent the first probe first?
