\figurewidth is not a dimension. I guess the following should work:

\def\LPscale{.6315789} % downscale the image
     \ifvmode
        \getfiguredimensions[\bufferprefix  
lilypond-\the\lily!figures.pdf][]%
        \leavevmode%
        \newdimen\FigWidth
        \newdimen\FigWidthReal=\figurewidth
        \FigWidth=\dimexpr(\LPscale\FigWidthReal)
        \ifdim\FigWidth>\localhsize
          \!!dimena=\localhsize
          \advance\!!dimena by-\FigWidth
          \noindent\hskip\!!dimena
        \fi
     \fi
     \externalfigure[\lily!img][scale=\dimexpr(1000\LPscale)]%
