[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")
`------------------------------------------------
