I'd use out-of-universe release order only if all the following are true:
 * 1. The stories were released in the same medium
 * 2. If televised, the stories were released as part of the same series run (same definition of "series run" as in the ongoing two-parter discussion)
 * 3. If the Doctor appears in both stories, he is in the same incarnation
 * 4. There is no in-universe evidence, including "incidental" evidence such as clothing, to suggest the stories take place outside release order
