My logic is this:

$formatters is an array of functions which are pipelined in reverse order.
You want angulars numberInputType formatter to run first, followed by your own smNumberFormat.
The two directives push their formatting methods into the array.
The order in which they are pushed depends on the priority order of the directive (higher numbers are compiled first)
The angular priority is 0.
So giving your directive priority *greater* than 0 should put your formatter first in the array and angulars second.
Since they are pipelined in reverse order that should give you the desired behaviour.

So you want a priority > 0 for smNumberFormat

UPDATE: Again I could be wrong. angular docs state the directives with a higher priority are compiled first but post-link functions are run in reverse order and I'm not sure what applies in this case. Maybe your directive *should* have a negative number.

IAC, one or the other should work :-}
