I believe you need to put \scoreAOboePart in its own nested StaffGroup:

%%%%
\new StaffGroup <<
  \scoreAFluteIPart
  \scoreAFluteIIPart
  \new StaffGroup << \scoreAOboePart >>
  \scoreABassoonPart
> >
%%%%

That should show a bracket only when the secondary oboe part appears, 
otherwise the bracket for that group will be hidden when there is just 
the one staff.
