Hi,

This callback OnEnterExitModShop, when player enter mod shop, is called before or after player interior change?

Well I don't know when but you can check it by just adding messages on callback and on function:
GetPlayerInterior(playerid, modshopid)
Now if the callback msg is second than then it is called after interior change.
I think you should have understood.

You could easily write a script that will tell you that via having everything (OnPlayerInteriorChange, OnEnterExitModshop) report back current statuses, and monitor for changes...
