How do you think PPD and CPD or Gutenprint can interact with the SCPS tag?
So you expect the tag to be preserved after the PDF rasterisation? Then 
pdftoraster would be somehow involved. I would like to read more 
descriptions about the intented stage in the process and implementation 
details. That could greatly help.

[Gutenprint has annouced support for the ColorKeyWord colour tagging of
  options. That information would cover all options of State 1 - 4.]
