nice! (will this end up on mutopia?)

You could use something like this (based on print-circled-text-callback in 
scm/output-lib.scm) to achieve what you want more cleanly. It works with 
2.5.19, but not with 2.4 for some reason.

\version "2.4.0"

#(define-public (print-+100-text-callback grob)
  (let* ( ;(text (ly:grob-property grob 'text))
         (text (number->string (+ 100 (string->number (ly:grob-property grob 
'text)))))
         (layout (ly:grob-layout grob))
         (defs (ly:output-def-lookup layout 'text-font-defaults))
         (props (ly:grob-alist-chain grob defs))
         (text-stencil (Text_interface::interpret_markup layout props text)))
    (ly:stencil-add (centered-stencil text-stencil))))


\new Staff {
        \set Score.barNumberVisibility = #(every-nth-bar-number-visible 1)
        \override Score.BarNumber  #'print-function =
        #print-+100-text-callback

        \repeat unfold 9 { c1 \break } \bar "|."
    }

HTH,
