I edited the priority values. The priority has an ascending order, so the values should ensure loading the first package first and the second one last…
So far it looks primissing. Will have to test after a PC reboot, but it still worked after several sim restarts…
Your findings align with our expectations, as Asobo has stated that the priority tag is no longer the preferred way of defining the order. We brought this up in our support ticket here:
With the release of SU2 today I can still confirm that the navigraph navdata not always replaces the in-sim-navdata when installed.
For me it only works reliable when I add the deprecated priority attributes.

Edit: as I cannot reply to this topic I would like to add the following here:
The order hint does not work reliable. Only by adding the priority attributes I am able to use navigraph navdata every sim start. Otherwise I end up with the in-sim-navdata sometimes…
The loading order with SU2 and the new package order hint tag is working correctly, and as ASOBO wrote in his answer, you can use the priority attribute as a fallback.
