More DFRPG questions: Bonus damage, omens, scrap, and flex armor

[tbone]

More questions, for any souls kind enough to weigh in:

1) In Monsters, hobgoblins and orcs have saw-toothed falchions that appear to inflict normal damage, +1 HP follow-up bleeding damage for the rough edge.
Is this special ability of saw-toothed weapons covered somewhere in GURPS rulesdom, or is this a one-off rule?
(If the latter: No complaints here; I like my standardized, unified rules at least as much as the next geek, but one-off oddities aren't out of place in the DF genre. That said: If saw-toothed weapons offer this damage bonus for free, won't every PC want one?)

2) Also in Monsters, skeletons appear to do thr damage (1d-1 for ST11) with a small shield, which looks fine. But they also appear to do thr damage with a "Bony Claw", when a punch should be thr-1 damage. Brawling skill isn't high enough to account for the extra damage.
Is there something that accounts for the extra damage? Maybe it's the "bony" that does it; is that a part of skeleton-related rules elsewhere in GURPS? (It really doesn't matter; just curious.)

3) What is the clerics' trait Divine Omens (14 pts) built fr... Never mind, I just found it: Oracle (BS 72). Next...

4) Exploits 16, under "Scrap", says: "Make one Scrounging roll for the party at the adventure’s end. Success means the junk might be of some value to someone. Failure indicates it really is garbage."

Is the intent here that a) the PCs roll Scrounging while surveying the ruins of dungeon they've defeated, to determine whether there's anything worth hauling back to town; or b) the PCs first haul the scrap back to town, then roll Scrounging to determine whether it's worth something?

(I'm pretty sure it's the former; it makes sense. But should Anyone Official wish to chime in with "Yes, doofus, that should be obvious...")

5) Am I missing something, or does DFRPG totally leave out rules for flexible armor & blunt trauma? (Given the modest armor DR available in this low-tech setting, leaving these out would seem understandable.)

Thanks, all –
