Thanks for raising this concern around tagged place and content sorting. I've researched this and believe this is a limitation of earlier versions of Jive, as reported in an internal improvement that was filed. I've tested this against Jive 8 and see that it is working using the "Sort by title" function. It also appears to be working in Jive 6.0.5:
Since Jive 6 is at end of life (see Customer FAQ & Associated (connected) Services and Jive 6 EOL), I would recommend upgrading to the latest version of Jive to take advantage of this and other bug fixes and improvements.
Let me know if you have any other questions with this.
Thanks for the update, Jeph. I'm just an end-user, so the decision to upgrade is waaaay out of my hands. But I appreciate knowing that it's a known issue.
