Look into your printer's PPD for the duplex related keywords. I suspect that 
the keywords in the PPD are named
KMDuplex 
or the like, and probably the pstops filter doew not recognize these alias 
names.
As a aorkaround, either replace the sides=... by KMDuplex=true (or what your 
PPD tells), or edit the PPD and delete the "KM" prefix from the respective 
keywords.

In addition, you might file a feature request for the pstops filter to 
honour the KM... keywords (and possibly more as needed).
