@FadedGiant, I finally managed to look it up. I would assume the name construction rule P-31.1.1.1 applies generally, even though the examples are bicyclic. (If I'm interpreting it correctly, that suggests that cyclohex-6-ene-1,2,4-triol is wrong, possibly the first time I've seen ACD get it wrong on such a simple thing.) I'm a bit more concerned about P-31.1.4.2, which has a different context as you pointed out...
I was probably reading the previous section on monocyclic compounds and didn't realise it had moved on to a new one. :) But I am not sure where else to turn to for this. The natural choice is P14.4(e), but it doesn't say much.
Well, actually P-31.1.1.3 explicitly says that P-31.1.1.1 is applicable to the monocyclic context. So we're ok there. Perhaps the alternative explanation is that the locants for the double bond are (1,2) and (1,6), although "only the lower locant for a multiple bond is cited" in the name. I always thought the locant for a double bond was the number in the name.
