That would indicate one of two possibilities. Either:
1) Everybody in the PEP 393 discussion except for you is clueless
about how to implement a Unicode type; or
2) You are clueless about how to implement a Unicode type.
Taking into account Occam's razor, and also that you seem to be unable
or unwilling to offer a solid rationale for those thoughts, I have to
say that I'm currently leaning toward the second possibility.

libfrancais does not appear to be publicly available. It's not listed
in PyPI, and googling for "python libfrancais" turns up nothing
relevant.
Rewriting the example to use locale.strcoll instead:
>>> li = ['noël', 'noir', 'nœud', 'noduleux', 'noétique', 'noèse', 'noirâtre']
>>> import locale
>>> locale.setlocale(locale.LC_ALL, 'French_France')
'French_France.1252'
>>> import functools
>>> sorted(li, key=functools.cmp_to_key(locale.strcoll))
['noduleux', 'noël', 'noèse', 'noétique', 'nœud', 'noir', 'noirâtre']
# Python 3.2
>>> import timeit
>>> timeit.repeat("sorted(li, key=functools.cmp_to_key(locale.strcoll))", "import functools; import locale; li = ['noël', 'noir', 'nœud', 'noduleux', 'noétique', 'noèse', 'noirâtre']", number=10000)
[0.5544277025009592, 0.5370117249557325, 0.5551836677925053]
# Python 3.3
>>> import timeit
>>> timeit.repeat("sorted(li, key=functools.cmp_to_key(locale.strcoll))", "import functools; import locale; li = ['noël', 'noir', 'nœud', 'noduleux', 'noétique', 'noèse', 'noirâtre']", number=10000)
[0.1421166788364303, 0.12389078130001963, 0.13184190553613462]
As you can see, Python 3.3 is about 77% faster than Python 3.2 on this
example. If this was intended to show that the Python 3.3 Unicode
representation is a regression over the Python 3.2 implementation,
then it's a complete failure as an example.
