The PythonScript 
automagically-turn-request-parameters-into-script-parameters feature 
only works when you directly request a Python script. But if you make 
your script this it will work::

  return "Hello %s" % context.REQUEST.name

It shares the same REQUEST object, as you expected. Notice that the 
script, besides accepting parameters, can also get the acquisition 
context and the DTML namespace (if called from DTML), so there's usually 
no need to use the REQUEST as a way to pass data around.
