I think, this is correct behaviour:

  Python is not statically typed. The same name can be bound to different
  types over time.

  The fact, that your argument has a list as default value does
  not mean, that all passed in values will be lists.

  The parameters passed with any Web request *ARE* all strings
  in the first place. Zope uses various ":XXX" suffixes to
  the parameter names to control how these strings are converted
  into other datatype (see e.g.

    <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html>

  ). But the "Test" interface of "PythonScripts" does not support
  these conversion suffixes.

  I agree, this is a limitation, but not inconsistent...
