Yup.

Why should it work so?  baseline-skip is a markup property and it
works inside the markup.
For changing distance between TextScript and the notes, try changing
TextScript's padding property.

But it does: in the last example the sharp is closer to the turn than
in the second one.  It's just that setting baseline-skip below some
value has no effect because LilyPond will not allow collisions between
objects.
