Is there some property that you know of to set in the PDF for showing that this field is reversed?

Try to set the /BlackIs1 parameter, or use /Decode [1 0]. In my experience, the /CCITTFaxDecode filter exactly reverses the meaning of those parameters, despite what the PDF spec says. For the rest, the PDF spec is very enlightening; practically all flags you can find in a TIFF can be set in the PDF as well, also for the other compression methods. You can find the spec at http://partners.adobe.com/asn/developer/technotes.html or thereabout.
