There is a function that is used for tags completion:

,----
| org-global-tags-completion-table is a Lisp function in `org.el'.
| 
| (org-global-tags-completion-table &optional FILES)
| 
| Return the list of all tags in all agenda buffer/files.
| Optional FILES argument is a list of files to which can be used
| instead of the agenda files.
`----

Maybe you can use that to loop over tags - depending on how you organize
your files and how you arrange the loops, there might be significant performance
differences, so you might want to experiment.

HTH,
