... not as an attempt to help, but rather to discuss once more.

Please take a look at this:

\version "2.13.22"  % 2.12.3 does the same here

\relative c'' {
  \once \override TextScript #'Y-extent = #'(1 . -1)
  \once \override TextScript #'Y-offset = #0
  \textLengthOn
  c -\markup \concat { \hspace#1.5 "script" } c c c
}

Here 'Y-extent for TextScript is set for something "unreal", "in order to make
a grob take up no [vertical here] space at all" (see the note for
'extra-spacing-width at IR 3.3). After that it's possible to specify it's
'Y-offset (its baseline) from the middle line "transparently" to other
objects --- so, it will be overwritten by others. To prevent this i've set
\textLengthOn and started markup with some space.

I was discouraged to do things like that (such 'Y-extent i mean) [1], however
i could not find a better way to do this for DynamicLineSpanner, for example.

Surely, would like to know a better way to do that, for any object, either
TextScript or DynamicLineSpanner.

Sorry, very probably this is a bad advice!
