So I suspect the --set-last-working shall be limited to the
tinderboxes that build regularly with a non-changing setup, i.e.
without having random other stuff that might affect the build-result?

never used the notes feature - but its help says that it can list the
notes - so no parsing of the full log necessary, just using "git notes
list" and iterate the list of note-object until the "magic string" is
found, and then checkout the corresponding annotated object.

or if one wants to parse a log, one can do it with

git log -p `git notes get-ref`
that way one only has to examine the ones that match. or can do a

git log -p -S"win32 working build" `git notes get-ref`

and only get the commits with a corresponding match.

The annotated commit is extracted from the "+++ b/<commit-hash>" line

See above - can combine the two methods :-)
