But the tempo indication is created by the MetronomeMark engraver, so
I'll have to wrap my tempo indication into a \mark construct ... that's
probably one way to go, but it's rather clumsy.

But why does LilyPond seem to ignore '(left-edge)? Is this a bug?

... or is it just that the MetronomeMark interface does not support all
options?
