I would doubt the quality of tags maintenance at Github, too. E.g. https://github.com/python/cpython/pull/12131 is labeled 3.7 and 3.8 at BPO but has no backport tags whatsoever at GH.
So the search you gave is clearly insufficient.

Tags maintenance isn't about quality but rather about automation. Things without backport tags won't get backported unless somebody does it by hand. And even automatically created backports need to be created off of committed pull requests and need to pass tests to be mergeable. Given the limited time until the Monday cutoff, I'd say that almost all of your 700+ BPO open issues that list 3.7 as affected will miss the boat on the fixes.

Except they are not "mine" but everyone's.

I'll have some downtime next week so I could look into adding stuff to automatically update labels on existing issues and PRs upon release of a new major version to, say, bedevere. The lack of this is the reason for the discrepancy.
