If you have the GPS/Compass module's arrow pointing to the front of the vehicle then you would want to select APM with external compass which rolls the compass Z axis 180 degrees because the compass on the GPS/Compass module is upside down compared to the normal mounting of the internal compass on the APM.

This is correct. The orientation of the external compass is in relation to the orientation of the APM, not of the vehicle's frame.
