Actually there is a code reference for your sconces actually not the sconces but in reference to :
(3) Bathroom Branch Circuits. In addition to the number of branch circuits required by other parts of this section, at least one 20-ampere branch circuit shall be provided to supply the bathroom receptacle outlet(s). Such circuits shall have no other outlets.
Exception: Where the 20-ampere circuit supplies a single bathroom, outlets for other equipment within the same bathroom shall be permitted to be supplied in accordance with 210.23(A).
.. So the sconces are ok, as far as I cant tell as long as it does not exceed 50 %(210-23)..
