This is a good question. I don't have the CD-ROM available at the moment, but I don't recall any detailed discussion of dating methods by the Society. I think it's a matter of "don't ask, don't tell". The Society knows that it doesn't have a self-consistent stance (esp. since dating methods are somewhat verified by each other) and so it knows that simply not discussing the subject is the best policy.
Since you mentioned the strange stance that some creationists follow in suggesting that the decay rate of C14 changed over time, here's an interesting fact: the rate of creation of C14 is determined by the amount of radiation that passes through the atmosphere from outer space. If something major happened to the atmosphere, say, 4800 years ago, that allowed more radiation to enter, then that would radically alter the production of C14. Other factors such as the magnetic field and volcanoes affect C14 levels. However, scientists sound confident that other dating methods have now confirmed the general accuracy of C14. So a number of years ago, the Society could have attacked C14 dating with some confidence, but nowadays it's just one of many dating methods in use and they can't attack them all.
