[Zope] reversing a LazyMap from a Catalog

[notices name]

Hi. I'm very new to all this, and I have a wierd problem with my catalog results. I have four catalogs, which I update in a batch from mysql. I find that if I query MySQL with an ORDER BY title DESC, then my catalog searches give me results in alphabetical order, which is great. Now, if my searches have no results, I'm supposed to give the user the whole contents of the catalog (thank god for batching!). I did that by setting the search terms to "" in the request, but it comes out in reverse alphabetical order. I tried to use the list reverse function, but the result seems to be a LazyMap, not a list and I can't figure out how to reverse it efficiently. I also tried request.set("sort_on","title"), but that doesn't work because it's a text index, not field.  Any ideas? Thanks a lot,
Annie

This script piece gets the catalog results. It is called from the results page. 

if not(request.has_key('all')):             # check to see if user wanted the whole list
        found = container.np.pc.pcCatalog()    
        if len(found) > 0:
            return found                        # if there was a result return it  
        request.set("badsearch","true")   # if not, set flag for badsearch message 
    request.set("city","")                     # clear search terms from request
    request.set("state","")
    request.set ("title","")
    return container.np.pc.pcCatalog()   # this returns the whole catalog in reverse alphabetical order??


This script piece loads the urls from mysql
#empty the old urls      
objectsToDelete = context.np.pc.objectIds('newspaper URL holder')
context.np.pc.manage_delObjects(ids=objectsToDelete)

#add the new
id = 0
for record in container.pc.getPcUrls():
    id=id+1 
    idstring = str(id)    
    context.np.pc.manage_addProduct['newspaperURL'].newspaperURL.createInObjectManager(idstring, context.REQUEST)
    newURL = context.np.pc[idstring]
    newURL.manage_editCataloger('pcCatalog')
    newURL.propertysheets.newspaperURLProperties.manage_changeProperties(req,city=record.city,state=record.state,newspaperurl=record.web_url,deviceType='pc',naaid=record.naaid,title=record.newspaper_name)    
    newURL.reindex_object()
