Unfortunately lilypond doesn't support musicxml at all, which is a bummer. I do the opposite route. MuseScore -> musicxml -> my script -> lilypond/musicxml -> PDF/MuseScore. I need this because, sometimes I want auto-generated annotations to my score. Say I write a phrase in MuseScore, I'm interested in the script adding a text with chord names, or pitch Set Class etc. MuseScore can do this with plugins, but I personally find MuseScore plugin system very buggy and hard to program. Python is much much much better and musicxml is pretty easy to deal with.
