I use:

above = { \once \override Script #'script-priority = #-100 }
below = { \once \override TextScript #'script-priority = #-100 }

mordentsharp = ^\markup \left-align \center-column {
 \musicglyph #"scripts.mordent" \raise #1.0 \tiny\sharp
}

And then one sometimes has to put in the \above or \below before the note. For 
example:
  g8\mordentsharp … \above a8\trill^\markup{\flat}
