I think I've only ever cared about two things wrt tag order: Getting the Signed-off-bys in order because that has relevance in tracking the origin of the patch, and putting my Signed-off-by last because that was where everyone and their dog put it when I started doing kernel work. If you want to encourage some uniform style, go for it, but please let's not start nitpicking and having people resend their patches just because they didn't put the tags in the order.
