I don't see any reason why CUPS should not recognize the syntax in
the PPD file (as long as that syntax is "legal" according to the
official PPD syntax specification as per Adobe's documents).

You can test this by running

   cupstestppd /path/to/PPD-file
   cupstestppd -v /path/to/PPD-file
   cupstestppd -vv /path/to/PPD-file

CUPS itself does not need to *understand* what exactly is contained in
the individual commands/code that drive your desired optional tray.

CUPS only needs to understand how to insert that code into a PostScript
file, and where in the file to do that.

That file then is sent to the print device, and the device's PostScript
interpreter now needs to understand and apply that code.

(If it now fails, you'll more likely have a bug in the printer or the
PPD itself than a bug elsewhere.)
