I don't understand how staff-padding relates to this discussion.
It counts from the reference point of the markup, which for text
is usually the bottom. Consequently, it does not align consecutive
scripts as if they were set as a line of text. To wit:

{
  \override TextScript.padding = ##f % now only staff-padding counts
  c'1^"afg" c'^"aht" c'^"afg"
}

Did you mean "Score.RehearsalMark" instead of "MetronomeMark"?

Apart from that, RehearsalMark doesn't listen to staff-padding,
only to padding
(https://gitlab.com/lilypond/lilypond/-/issues/342)
but I don't think this matters for the present discussion.

As a side note, right now, side positioning is done via skylines,
which is a bit different from just using the reference point.

That doesn't change the fact that markups made of letters with
varying heights have their bottoms aligned when there aren't
any objects nearby that they need to avoid, which leads to the
problem at hand.

For a start, this can be useful:

{
  \override Score.RehearsalMark.Y-offset = 4
  \mark \markup { agt } g'1
  \mark \markup { aht } g'1
  \mark \markup { agt } g'1
}
