Summary: InvokeTypes returns int instead of PYIDispatch object

Initial Comment:
Python program fragment. Assumes excel dispatched as a
COM object, with a worksheet with a chart:

sc = chart.SeriesCollection()
sc.Add(series_range, seriesAddDirection)

The last line causes an error. Here's the method code
generated for Add by the dispatch module:

def Add(self, Source=pythoncom.Missing, Rowcol=2,
SeriesLabels=pythoncom.Missing,
CategoryLabels=pythoncom.Missing,
Replace=pythoncom.Missing):
        ret = self._oleobj_.InvokeTypes(181, LCID, 1,
(9, 0), ((12, 1), (3, 49), (12, 17), (12, 17), (12,
17)),Source, Rowcol, SeriesLabels, CategoryLabels, Replace)
        if ret is not None:
                ret = Dispatch(ret, 'Add',
'{0002086B-0000-0000-C000-000000000046}',
UnicodeToString=0)
        return ret

The call to InvokeTypes returns integer 1 rather than a
PyIDispatch object.

Originally reported under Bug 841605. Creating new bug
since I have researched this in much more detail than
before. 

This is as far as I can go without help. I have clients
waiting to use my program as soon as we can fix it.
