Rank refers to how many times the mod has been upgraded, and is indicated by the number besides the rarity. The rarity itself, however, is not taken into account.

After a brief inspection of this, it appears to sort by where the mod is used (i.e. warframe, rifle, etc.) after sorting by rank. rather than rarity.
