Thank you.

However, Org 9.X still supports Emacs 24, so we cannot use
`string-collate-lessp without degrading gracefully to `string-lessp' in
these Emacsen.

We could add `org-string-collate-lessp' to "org-compat.el", which would
be an alias for `string-collate-lessp' on Emacs 25+ and to
`string-lessp' otherwise.

Return non-nil if...

We would also need tests for that feature.

WDYT?
