It largely seems reasonable to me.  Presumably it would work like
the specificity of :matches() as described in
http://dev.w3.org/csswg/selectors/#specificity

Though it's a little bit interesting that:

  :nth-child(odd of p, .byline)

would have specificity (0, 2, 0) for the #byline and (0, 1, 1) for
the p.  I guess that's probably ok, though.
