Ah, that explains everything!  Because text on an axes3d object has to be
projected to 2d, it uses simple AGG text rotation behind the scenes to
achieve that effect (rather than actually performing the expensive tedious
calculations to fully project it).  So, even though you are not rotating the
text, mplot3d is.

Good to know that switching to GTKAgg fixed everything.
