[Zope] How to filter and sort PropertyObjects from ZCatalog

For the 'filter problem', I found a possibility:

result = (map( lambda brain: brain.getObject(),
         filter(lambda x: x.getObject().getProperty('priority')>0,
         container.Catalog.searchResults())))

Stays the 'sort problem'...
