Oh, simple...

In the main PDox folder, there are *.SOR files.

For Paradox-Interactive:
   - The active sort-order is in PARADOX.SOR.
   - Close Pdox-Interactive.
   - Maybe keep a backup of PARADOX.SOR.
   - Copy whichever SOR file you prefer to PARADOX.SOR
   - Start Paradox, etc!!!
   - Close when done!
   - Rename that backup to PARADOX.SOR.

For Paradox-Runtime the exact same steps apply, but the active SOR file 
is named PDOXRUN.SOR.
