Either I don't understand what you're doing, or you haven't properly understood 
the use of \tag.

I'm suggesting that you do something like

\version "2.13.9"
notes = \relative e'' {
   e4 \tag #'MS {e} \tag #'corr {d} c d   |
   e e e2   |
}
\markup { ORIGINAL: }
\score { \keepWithTag #'MS \notes }
\markup { CORRECTED: }
\score { \keepWithTag #'corr \notes }

Clearly, this doesn't require tagging "every note with a different tag" — you 
simply tag the notes for different editions as you need them.
What am I misunderstanding about your particular situation?

Cheers,
Kieren.
