One common case where Luck is a better choice than order is in provinces that you are blood hunting. If you are playing one of the Mictlans, and you have blood hunters on every province from 2000 to 10000 pop, then Order is almost useless. And in general, as the game wears on and more and more disasters, pillagers, and spells hit your provinces, the value of Order becomes less and less. Plus, Luck makes the various Cross Breeding spells potentially worthwhile.

I would also point out the player morale benefit of Luck. When your neighbors are declaring war on you left and right, it is good for your spirits when a random gift of 1000 lbs of gold arrives at your capital.
