Well, there may be two different applications for the barnumer in play here. An 
annotation includes a reference to the position, so it can say "in m. 23, 3rd 
beat, violin2" - and that measure is expected to be the measure that will also 
be printed rather than an internal counter.
But even if the grobs themselves only record that "natural" position I can't 
imagine there's no way to get to the barnumber of a given note column (maybe 
that's better than a grob itself) as seen by Score.currentBarNumber and printed 
by the bar number engraver.
