Python 3.x is not guaranteed to be backwards compatible with Python 2.x,
and I don't think Lilypond has been ported to Python 3. So you probably
do need to be running the earlier Python version with lilypond-book.
Why it should give an error after you changed the PATH back to what it
was before, I don't know... :-(
