comment Best way to find permutation with specific total
@ David Carraher - Your total comes out right (19.6m). Try running Length[Permutations[#]] & /@ combos // Total again.

comment Best way to find permutation with specific total
Very nice. 13 seconds for all permutations: Timing[Partition[ Flatten[Permutations /@ IntegerPartitions[24, {12}, {0, 1, 2, 3, 4}]], 12];]

+1 But I used Partition[Flatten[Permutations /@ combos], 12] // Length to obtain the 19611175 permutations.

So I see, 19,611,175. Just a better method than counting through would be good. I'll see about editing the question.
