Yes I'm sold too, in current state of thing (with XEP-0060 being stable), the 
best option to fix that is to go with XEP-0413. I think that It should be 
spelled out clearly that ordering is implementation dependant in XEP-0060.

MAM ordering is an important use case, I'm already using it for full-text 

Besides, MAM is even useful for generic pubsub use case (i.e. without search), 
as it returns items separately in messages, while pubsub returns everything in 
a single stanza. Returning everything in a single stanza is flawed because you 
can easily reach the stanza site limit of your server, I've already been hit 
by that (while speaking about it, I realise that MAM example are incorrect in 
XEP-0413, they are not returned with messages, I'll fix that in next revision).
