[Zope] DTML-tree Custom sort

[Alex Renier]

Hello,
I am trying to do a custom sort.  I am using:
<dtml-tree branches_expr="objectValues(['Folder'])"
sort="orderInt" skip_unauthorized>

orderInt is an integer property of some folders.  I
would like the <dtml-tree tag to look up the property
of the current folder and sort based on the integer
value, but if the property does not exist I would like
it to be excluded from the tree.  Is there a way to do
it? 

Thanks for any help!
