This Tampermonkey script will auto-click the comment sort link in JIRA if it detects comments are not sorted in the order you prefer. By default the script will sort comments in ascending order (oldest first), but you can easily change this by editing the script.
This script is necessary because JIRA only has a single, site-wide comment sort option, and if you prefer comments sorted in the opposite direction as your site administrator, you will have to constantly fix the sort order manually, after some number of hours or days when your session resets, and likely only after you've realized you've been reading comments in the wrong order. This script relieves this constant source of frustration. It's only a workaround until Atlassian can implement Store comment sort order in user profile (JRA-5443). However this ticket has been open since December of 2004, so I wouldn't count on it anytime soon.
It seems to work well. It's possible different versions of JIRA will change the HTML element names, so it may need to be adjusted over time. Another thing I did was intercept the scroll down that happens when you click the sort order link. I tested it on my own JIRA server (v7.1.8#71012-sha1:d834917) and Atlassian's current version (at jira.atlassian.com). Improvements/assistance and Pull Requests would be greatly appreciated.

Tampermonkey will now show you the script so you can review what it does. Click Install.
-
At this time, you must edit the script to add the appropriate
@matchtag(s) so it runs on your JIRA servers. Click the Tampermonkey icon in your browser, go to Dashboard, click the script, add the@matchtag(s). If you also wish to force comments to be sorted in descending order, change that now. Finally, click the Save button. -
That's it! You can test it by going to your JIRA server, reversing the comments, and reloading the page.
