[Zope] Custom sorting

[Bjørge Solli]

I want to make users who upload some files, arange the order of the files 
themselves. I plan on doing this by adding a property to each file named 
'sortorder'(int). And then order on this property. I think this is a bad 
solution, since it means when a user wants to insert a file as #2, I have 
to update all the other files who has sortorder>=2. So is there another 
way of doing this?
