That statement in braces 
{ /Duplex true def} if
only gets executed if the pdftops utility (called from my filter script) is 
configured to force duplex by the respective statement in the config file.
I guess you have set
psDuplex yes
in the config file. You should set this to no (or delete this statement, as 
no is the default) and configure the default duplexing using the respective 
PPD option so that duplexing is selected by the pstops filter. Then your 
"sides=one-sided" will take effect.
