That combines a Script (articulation) with a TextScript (markup), which isn’t 
my favourite solution.

I would try something more like this:

\version "2.19.82"

mordentsharp =
  -\tweak Script.text \markup {
      \override #'(baseline-skip . 1.25) \center-column {
      \fontsize #-2 \sharp
      \musicglyph #"scripts.mordent"
  } }
  -\tweak Script.stencil #ly:text-interface::print
  -\tweak Script.X-offset #-0.3
  \mordent

{ c'1\mordentsharp }

That way, it’s all one Script, which can then be manipulated as one, if 
necessary.

Just flip the position of the \sharp and \musicglyph in the function.  =)

Hope that helps!
Kieren.
