One oddity is that repeatedly reverting the buffer swaps between the
"correct" overriding column format and the default.

It seems like what is happening is that the org-agenda-prepare and
org-agenda-finalize calls in org-tags-view are swapping
org-agenda-overriding-columns-format (ocf) on and off.  I added debug
messages around these points, and a cycle looks like:

@@@@@@@ before prepare "%TODO %60ITEM %SCHEDULED"
@@@@@@@ after prepare "%TODO %60ITEM %SCHEDULED"
@@@@@@@ before finalize "%TODO %60ITEM %SCHEDULED"
@@@@@@@ after finalize "%TODO %60ITEM %SCHEDULED"
@@@@@@@ before prepare "%TODO %60ITEM %SCHEDULED"
@@@@@@@ after prepare nil
@@@@@@@ before finalize nil
@@@@@@@ after finalize nil

During the first cycle, prepare doesn't unset the local value for ocf
because it's not set, then in finalize the local value of ocf is set
using the current dynamic value.

During the second cycle, ocf is set locally so prepare wipes the local
value.  It looks like this also wipes the current let-bound dynamic
value for ocf, so during finalize ocf is not (re)set as a local value.

Go back to first cycle.

I don't see an easy good fix due to how Emacs's dynamic variable
binding works with respect to buffer local variables.

One way to fix is redefine:

(defun org-let (list &rest body)
  (eval `(with-temp-buffer ,(cons 'let (cons list body)))))

That way, the let doesn't use the buffer local value for ocf, so the
kill-all-local-variables doesn't wipe it.

I can confirm that this fixes this bug.  However, I have no idea what
effect this may have on all of Org mode.

This does not work for obvious reasons, please don't use it.  I'll
shut up now since I clearly need sleep.

I think the right way to fix this is by using a separate variable for
setting buffer local values.

I have attached a patch implementing this on maint.

You need to include variables and functions modified in the commit
message, so grepping through them more fruitful.

Since this is a local variable, `setq' is enough, isn't it?

The first line of a docstring cannot contain an incomplete sentence (due
to `apropos` design).

The two variable names are somewhat confusing. Could
`org-agenda-local-overriding-columns-format' be renamed into
`org-local-columns-format'? Since it is defined in "org-colview.el", it
doesn't deserve the "org-agenda" prefix (and neither does the original
`org-agenda-overriding-columns-format'.).

I don't know if the defvar-local in org-colview will be loaded before
this point,
so I think it's safer to just use setq-local.
