"out" params are best supported if the object supplied a typelib - then 
Python knows the params are out and does the right thing automagically. 
  If out params are detected, the result of the function will be a tuple 
of (real_result, out_param1, ...)

Even if no typelib is supported, you can access them with a little pain 
via the win32com.client.Dispatch() object.  You might like to follow up 
to the python-win32@python.org mailing list where many people will be 
able to help.

HTH,

Mark
