Category is part of DocSummaryInformation, so you'll need the PIDDSI*
constants instead of PIDSI*.  (PIDDSI_CATEGORY just happens to be
equal to PIDSI_TITLE)

from win32com import storagecon
import pythoncom
fname='c:\\tmp.doc'

pss=pythoncom.StgOpenStorageEx(fname, storagecon.STGM_READ|storagecon.STGM_SHARE_EXCLUSIVE,
    storagecon.STGFMT_DOCFILE, 0 , pythoncom.IID_IPropertySetStorage)
ps=pss.Open(pythoncom.FMTID_DocSummaryInformation)
print ps.ReadMultiple((storagecon.PIDDSI_CATEGORY,))[0]
