It does?  I've always been told that this is supposed to be roughly a
log of what happens.  In that sense you added your SoB before the
review/test happened so it should come before.  I know some
maintainers seem to do things differently but that seems to be the
most common.  In that sense, I think the order that Akhil has is
correct.  ...but, obviously, it's up to the maintainer.  ;-)
