In that case the reasonable way to do it would be by the flip of coin or other equal opportunity method of chance since both teams are equally deserving. Other ways they could do it are to go to regional competion results to determine a higher seed but that method is not necessarily "fair". In fact going by the divisional seeding results isn't necessarily fair either in my opinion because your rankings are not from playing the same teams so they really don't correlate. I would suggest the afforementioned coin flip or drawing divison names from a hat to level the playing field.
