Hi Paul,
Remembering that everything scripted must be able to be performed at the command line, I'd start with the "LAYOUT" command or "-LAYOUT" to Set or create a new layout.
Enter layout option [Copy/Delete/New/Template/Rename/SAveas/Set/?] <set>:
NOTE: You must either make sure each drawing already has a layout with the same name (so your script can function correctly on ALL drawings, or you must make a PRE run through your drawings to create a layout with a common name.
I'd experiment a little with the keyboard and see if you can manipulate your plot to the way you like using the "-PLOT" command once you are on the layout you want to use.
There is a summary of how to use the -PLOT command here:

I hope this helps you out... (I'm not sure if that's what you were asking?)
Regards,
Bill
