I've heard this story, but I can't find any evidence for "regularly". (I'm also not sure what form such evidence would take.)
The highest profile case I can find is of Robert Jordan, of New London, CT, who sued for discrimination because his job application was rejected for scoring too high [sic] on the IQ test. (He lost.) (http://www.nytimes.com/1999/09/09/nyregion/metro-news-briefs...)
It appeals to my own personal prejudices, but it was also 10+ years ago.
