You can use the REQUEST object to store evaluation results
to be used later. E.g.:
<dtml-call "REQUEST.set('actions',1)">
<dtml-if "action == 'insert'">
  ... insert ...
<dtml-elif ...
<dtml-else>
  <dtml-call "REQUEST.set('actions',0)">
  ....
</dtml-fi>

<dtml-if actions>
  .... updated order .....
</dtml-if>

Probably, Zope should have a "dtml-set" which would
allow to update a new "REQUEST.vars" directory.
Many questions in this list would go away, if assignment
could be done with an explicit dtml tag.
