What error results from trying that inside a Python Script?  Even
better, write up a unit test which:

  - Registers an adapter using the syntax you expect (might be a
    "dummy" version)

  - Creates and invokes a Python Script with an instance for which
    the adapter lookup should succeed.

  - Asserts that the result of calling your method on the adapter
    is what you expect.

Write it as either a "classic" unit test or as a doctest narrative, and
then we can all run it and see what happens.
