How about using ly:context-property-where-defined?
As in:


%%%%%%%%%%%%%%%
\version "2.19.82"

increaseBarNumber =
#(define-music-function (par loc addm) (integer?)
   (make-apply-context
    (lambda (context)
      (let* ((where (ly:context-property-where-defined context
'currentBarNumber))
             (cbn (ly:context-property where 'currentBarNumber)))
        (ly:context-set-property! where 'currentBarNumber (+ addm cbn))))))


testmusic = \relative {
  c'4 d e f g a b c d e f g a b c2 R1*3
  c4 b a g f e d c b a g f e d c2
}

\score {
  <<
    \new PianoStaff <<
      \new Staff { R1*22 }
      \new Staff{
        \testmusic
        <>^"↓ increase barnumber by 100"
        \increaseBarNumber #100
        \testmusic
      }
    >>
    \new Staff { \testmusic \testmusic }
  >>
}%%%%%%%%%%%%%%%

All the best,
Torsten
