Secondary sort order allows you to specify how you want the scenes sorted within the Primary groupings of Interior VS. Exterior, Location, Time-of-Day, or Characters. For example, Interior VS. Exterior as the Primary sort and Script Order as a Secondary sort would give this kind of breakdown:
EXTERIOR
1 HOSPITAL -- DAY 1-2 1 1/8
4 PARK -- DAY 4-4 2/8
5 HOSPITAL -- EVENING 4-5 6/8
--------
2 1/8
INTERIOR
2 HOSPITAL -- DAY 2-2 3/8
3 EMERGENCY ROOM -- DAY 2-3 5/8
6 EMERGENCY ROOM -- EVENING 5-5 2/8
--------
1 2/8
With Location as the Secondary sort, the same document would breakdown with the locations grouped together alphabetically:
EXTERIOR
1 HOSPITAL -- DAY 1-2 1 1/8
5 HOSPITAL -- EVENING 4-5 6/8
4 PARK -- DAY 4-4 2/8
--------
2 1/8
INTERIOR
3 EMERGENCY ROOM -- DAY 2-3 5/8
6 EMERGENCY ROOM -- EVENING 5-5 2/8
2 HOSPITAL -- DAY 2-2 3/8
--------
1 2/8
