Why Mathematica's built-in function 'Pick' does not work properly?

Questions
1

Does anybody know why something like e.g.

Pick[{c, l, s}, {2, 0, 5}, Except[0]]

does not work?

And by ‘does not work’ I mean that it returns {c,l,s} when it should have returned {c,s} (right?).

Is it a bug or is it a feature?

Pick[{c,l,s},{2,0,5},Except[0,_Integer]]

works. See the link
