If we assume the position of each scoop in the stacked cone of 4 scoops matters, but its position in the bowl does not, this reduces to a problem of permutation vs. combination.  For every combination of 4 scoops, they can be arranged in 4! = 4*3*2*1 = 24 ways.  So we need to divide 3024 by 24 to get the number of 4-scoop combinations that are possible.  3024/24 = 126 different bowls.
