+3 Tomes cant be found in any chest and are BtC, so probably (2).

Ah, so:
(1) Raids, except The Shroud, have special random loot tables which do include, depending on the raid, varieties of bound +2 and higher tomes.
I still hold that Occam's Razor supports the idea that +3 and higher tomes are part of the normal named loot of the raid; (2).
