So, what I ended up with was something like this:

allgrids=[[[grid1]],[[grid2]],etc.]
matchcount=allgrids *0b; initialize
for i1=0,ngrids-1 do for i2=0,ngrids-1 do matchcount[*,*,i1] +=
(allgrids[*,*,i1] eq allgrids[*,*,i2])
magnitude_of_mode = max(matchcount,dim=3,imode)
value_of_mode = allgrids[imode]

So 2 for-loops still needed, but across the shortest dimension.
