Hello Cade! As you might note with other posts at google groups, the community for this discussion has migrated to
talk.tiddlywiki.org.
Although we (at that forum) can still *see* posts from the google group, we can't reply easily to them.
So please come on over to google groups.
Meanwhile, I can suggest that the
documentation on the reverse Operator shows that it doesn't take a parameter, nor does it work as a parameter within the sort filter run prefix; instead it works at the "caboose" end of any filter to flip the list order. Something like this works at Tiddlywiki.com:
`{{{ [has[version]] :sort:version[get[version]] +[reverse[]] }}}`
