In order to install Wiremold metal raceway on the inside garage wall for

Wiremold that carries the 24v wiring for the sprinkler system.

Would it be kosher to have the new Wiremold simply cross over the top of
the existing Wiremold and thus not be flat against the wall for the
whole of its length? Or lift the existing Wiremold away from the wall
and let the new Wiremold pass under it and thus remain flat against the
wall? Or...?

You could install a surface wiremold box. Cut out the attachment tabs at
top and bottom (or sides) and run one wiremold straight through the box.
Terminate the other wiremold at the box normally and run the wires
through. You can't have the wires for both loose in the box. I would
strongly prefer to run the power straight through, but it would be more
work.

There are "bushings" that are required at cut ends of wiremold. You
probably already know about them.
