[ups ... I sent this unfinished by accident first]
Ok, thanks, this explains a lot, and it seems that Org-mode inserts the
:ARCHIVE: tag always at the end, and other tags in front of it:
,-----------------------------------
| ** Second Level 2 :tag:my:ARCHIVE:
`-----------------------------------
so it will almost always look like this:
,------------------------------------------------
| :tags ("tag" "my") [...] :archivedp ("ARCHIVE")
`------------------------------------------------
