Acknowledger order depends on the order engravers are \consist-ed (the
only exception is if you set must-be-last to #t)

If you want to do useful things to the NoteHead, you should wait until
all the acknowledging has finished, i.e., store the NoteHead grob and
process the information in a process-acknowledged or
stop-translation-timestep function.

BTW, if you're prepared to wrap the notes in a chord (so you have
access to 'articulations), you won't even need a scheme engraver (all
the processing can take place in the NoteHead's stencil callback).
