Sorry it took me so long to respond.  In section 9.2.1 (Common tweaks), it says

 % This will not work, see below:
          \override MetronomeMark #'padding = #3
          \tempo 4=120
          c1
 % This works:
          \override Score.MetronomeMark #'padding = #3
          \tempo 4=80
          d1
"Note in the second example how important it is to figure out what
context handles a certain object. Since the MetronomeMark object is
handled in the Score context, property changes in the Voice context
will not be noticed."

What I was suggesting was that when the \override does not
specifically mention a context, it should apply not to the current
context, but rather to the bottom-most active context that actually
has the relevant object.  The Voice context has no MetronomeMark, so
\override MetronomeMark in a Voice context should actually override it
in the Score context.
