This is what I call a two edged sword and potential gamechanger. Handled wrongly, it could cost you a job you would otherwise have. Handled well, it might get you a job you might not otherwise get.
The first thing to do is to evaluate your chances. If you appear to be a favorite, don't rock the boat too much or otherwise jeopardize your chances. You might point it out, but in a diplomatic manner suggested by others, and ask for the purpose, or if it was intentional, rather than an error.
If it is a crowded field, and you are otherwise a long shot, I'd take this opportunity to show what I could do, and point out the error. Again, a diplomatic approach is best, but not as crucial as in the first case, because you have more to gain than lose. One way or another, it will set you out from the "crowd," and one of these ways is a positive way.
I once read of a situation where the interviewer (and prospective boss) handed job applicants what was purportedly a company "package" with a deliberate misstatement. One of the applicants spotted the error and got back to the "boss." The others didn't. I don't need to say which applicant got the job.
