If you have 3 dice and 2 opponents you'd allocate 1 dice to one opponent and 2 to the other.
Whichever opponent you wanted or the least dice against the camels as they are causing the disorder. Otherwise, as camels are generally otherwise piss poor, most people would allocate max dice against the camels as there is more chance of hitting them/not being hit by them.
At impact 4 dice v's camels at + and 1 dice either side at evens is far better than 2 dice v's camels at + and 2 dice either side at evens
(edit) no its the same number of hit probability. But causing more hits on the camels gives a better chance of causing disruption as you can only do a max of 2 either side whereas the camels could take 4 by themselves depending on allocation.
It would make a difference against unprotected weaponless camels in melee though
