I know for a fact that what you said regarding BG:EE and BG2:EE is true. Only those three skills benefit from being higher than 100. MS and HiS because there are numerous sneak penalties that can bring down your scores in those skills (sneaking in daylight, particularly perceptive NPCs, etc.), and Pickpocket because there are a number of items that can only be stolen with skill scores above 100. Everything else doesn't benefit from scores higher than 100.
I am not as well versed in IWD:EE, but I would assume the same could be said mechanically for that game except for Pickpocket (that would depend entirely on what items can be stolen and whether they require scores higher than 100 to make the attempt). There are still penalties for sneaking in certain scenarios so MS and HiS should be higher than 100 if you're focusing on stealth, and the rest of the skills should cap at 100.
