You could try uninstalling both Python 3 and Lilypond, and reinstalling
them both...

Porting something to work with Python 3 is a non-trivial issue.  To give
you an idea of the range of needs out there, my Linux distro makes
available all versions of Python from 2.3 to 2.6 (the most recent 2.x
release) as well as 3.0 and 3.1 -- in order to support various packages.
 Conversely, a Python program that wants to be widely used has to work
with a range of different Python releases, since not everyone has the
latest Python available.  Porting to 3.x while still maintaining 2.x
backwards compatibility is a bit of a load to carry when 2.x is still
the most widespread Python out there.

... but you know that, if you're a Python dev -- so what's the chance
that you could put some work into the port? :-)

I'd also love to see xelatex compatibility, but don't have the faintest
clue how to start working on that.
