A while back I made myself this survival order of importance list:

1. Prevention (trip plan, geared right, planning ahead, avoiding risks)
2. Health (psychological stress, traumatic and environmental injuries)
3. Personal protection (clothing, shelter, insects, fire)
4. Signaling (fire, whistle, mirror)
5. Sustenance (water and maybe food)
6. Location & travel (using a map, compass, GPS)

I see it as kind of a higher-level view of priorities relative to Jim's list. Jim's is more of a to-do list, which is important when there are, well, to-do's to do.
