AIUI \relative { … } is an /input/ method: its rules apply as the
pitches (the "…") are read.

At the end of reading them, testNotes is handed a load of
/absolute/ pitches.

By this time, the tags are impotent.
You could split the testNotes into two sections, testNotesPartA
and testNotesPartB, and then write scores like:
\score {
\testNotesPartA
\testNotesPartB
}
and
\score {
\testNotesPartA
\transpose c c' { \testNotesPartB }
}
to get the effects you want. Perhaps you can tag a construction
like the following to make partB into one of two alternatives:
\score {
\testNotesPartA
«some sort of tag» \testNotesPartB
«another sort of tag» \transpose c c' { \testNotesPartB }
}
(IDK, I've never used tags.)
Cheers,
David.
