It works but doesn't seem optimal. Thankfully it will only ever be a small collection of 20 to 30 objects. I don't really notice any big hit on performance.

Did you take a look at the eBefore and eAfter parameters of the Add method?

for example:

loCollection	= createobject('Collection')
loCollection.Add('abc', '_123')
? loCollection.Item(1)  && abc

loCollection.Add('def', '_345', '_123')

? loCollection.Item(1) && def
? loCollection.Item(2) && abc

Another property that might help you is KeySort 0 - by index, 1 - by index desc, 2 - by key, 3 - by key desc
