CouchDB can generate time-based UUIDs, where the top part of the uuid is the
time and the bottom part is essentially random.

I think this would work very well for you:

- you get documents with equal keys naturally sorted by insertion time

- you don't even need to add a created_time field, since you can parse it out
  of the uuid when you need it
