With crooked floors, sometimes it's a bit of an art to disguise it within the tile.
Initially, I'd want to understand if you could split the 7/8" between both the baseboard course and the bottom course of tile. If so, it may be more disguised than forcing it upon only one. Is that a possibility?
Or you could think outside the box a bit. What about using a larger tile that would disguise an un-level line a bit better?
