I think it's a bit of a stretch to confuse the two, especially since the Elder Scrolls series games are known more by their subtitles (Skyrim in this instance).

I think it's a bit of a stretch to confuse the two, especially since the Elder Scrolls series games are known more by their subtitles (Skyrim in this instance). "Elder Scrolls V" doesn't exactly roll off the tongue. Sure, the trademark contains the word "scrolls", but by this logic no one could ever use the word scroll in a game title as long as the trademark is in effect. On the other hand it seems like it could be a good defensive maneuver, as a trademark by Mojang on the name "Scrolls" by itself could be a bigger issue down the road.
