These files don't make use of \c__keys_code_root_tl or \c_keys_code_root_tl, on my system it's only l3keys.sty    2013/02/24 v4461, that has \c__keys_code_root_tl. A final update might be useful… (since TeX Live has become stable a month ago)

All correct: there was a change, it was a while ago and provided you
have up-to-date fontspec and expl3 packages everything should work.
