I do not believe \midi can be used within a \markup \score.  At least, 
in my testing, it does not work.  The \score needs to be top-level.

If you need to keep your \score within the \markup, put the important 
bits in a variable and use it twice:

%%%%
\version "2.19.82"

stuff = << \new Staff { b'4 } \new Staff { \clef "bass" g4 } >>
\markup \fill-line { \score { \stuff } }
\score { \stuff \midi { } }
%%%%

That said, you can probably achieve what you want without needing to use 
\markup \fill-line for centering.  LilyPond already centers the music on 
the page, you just need to specify a smaller value for line-width:

%%%%
\version "2.19.82"

stuff = << \new Staff { b'4 } \new Staff { \clef "bass" g4 } >>
\paper { indent = 0 line-width = 1\in ragged-right = ##f }
\score { \stuff \layout { } \midi { } }
%%%%

This would require you to specify the width manually, but that might not 
be a bad thing.
