There are tons of extra "you can't take 10 if you..." but as far as I can tell, most of them are misinterpretations.
Taking 10 is the law of averages (rounded down). Any time a character is not in a stressful situation, they can do an average job if they want to. There is no skill I would not permit this on, given the lack of stress (although technically UMD is not permitted since there is a specific effect of rolling a 1 that the PTB wanted kept in...i could go either way).
Taking 20 is the joy of repetition. Any time a character can afford to try again and again and again till he finally gets it right, he can Take 20. Thus many skills don't qualify. Crafts (because of use of materials), Knowledge (you know it or you don't), UMD (because of charges/etc), Climb, Jump, and Swim (sometimes it might work but usually the consequence is fairly dire).
Really, it's designed for Appraise, Disguise (provided you have the time before anyone sees you), Decipher Script, Escape Artist, Forgery (although materials could come up in this one), Gather Information, Handle Animal, Listen, Open Lock, Search, Spot, Survival, and Use Rope.
