I found a similar question here dated way back to 2013:
Is it possible to order the JQL by transition date in the later verisons of Jira?
It looks like the solution proposed or one using a third party add-on is going to be the best way to go. There's a similar Community post titled Order-By-Date when an issue is moved to a specific status that attempts to do the same thing. Andrew provided a good workaround using the Jira Misc Custom fields plugin.
Take a look at the linked article and let me know if you have any questions.
