Even if you are the hardest person in the company to talk to, if you consistantly get what needs to be done faster, cheaper, and more reliably than anyone else, you'll be invaluable.
This is a dangerous generalization. Some corporate cultures will accept a higher level of eccentricity (and anti-socialism) in exchange for higher productivity. Other corporate cultures consider ability to communicate and work as a team as part of the definition of productivity.
In short, if you can't work with others, you put yourself at a large disadvantage. There are very few places where you can get away with being an "island unto yourself", whether that's because you are a boor, a chauvinist, smell bad, are pathologically shy, won't or can't communicate well, or what-have-you. Other co-workers will not be able to trust you, so why would they consider you a teammate or mentor?
And that's not even getting into the "political" ramifications of being non-communicative. Many decisions made by your employer will have other factors besides just your productivity. "Works well with others" is always a positive thing to have on a review.
