Hi Michael,
I guess I was confused by this paragraph in the docs at http://pypi.python.org/pypi/discover/0.3.2:
"""
If a test package name (directory with __init__.py) matches the pattern then
the package will be checked for a load_tests function. If this exists then it
will be called with loader, tests, pattern.
"""
I interpreted that to mean "if a test package name matches the *test* pattern
then..." which apparently it does not?

Good point; I was just confused by the docs.
