Hi Kieren,

how about the following? Uses
 - \with-dimensions to fake zero extent for the markup that should not 
be considered for spacing,
 - \halign to make it right-aligned, and
 - an \hspace inside all that to shift stuff slightly more to the left.
Still quite verbose, but no need to figure out any hspace values manually.

\paper {
  bookTitleMarkup = \markup \fill-line { \abs-fontsize #18 
\fromproperty #'header:title }
  scoreTitleMarkup = \markup \fill-line {
    \concat {
      \abs-fontsize #18
      \with-dimensions #'(0 . 0) #'(0 . 0) \halign #RIGHT \concat {
        \override #'(box-padding . 0.5) \box \concat { "#" 
\fromproperty #'header:no }
        \hspace #0.5
      }
      \override #'(baseline-skip . 0) \center-column {
        \abs-fontsize #18 \fromproperty #'header:title
        \abs-fontsize #13 \concat { "(" \fromproperty 
#'header:performers ")" }
      }
    }
  }
}


HTH,
