When I ran a poll for a similar list, before @Lyya’s awesome website superseded it, there was a strong consensus for sorting by GoW order:
The sorting order is consistent throughout the game, and mana is credited within the game in this order when there are multiple matches (Blue first, then Green etc.)
So, while I acknowledge that this might be non-intuitive for newer players, I would argue that the solution is for newer players to learn the GoW order, rather than Lyya change her website.
