It's also suppose to be a very rare spell to find a cleric able to cast. Lore wise, people who can cast 9th level spells are few and far between. Also, could the spell be used on Eberon, for example, to bring back someone who died in a completely different branch of reality? After all, the deity granting your chosen cleric's spells doesn't have any authority over the afterlife of Taylor's reality.
EDIT: Also, if you bring said cleric to Taylor's dimension, they may not retain access to their spells due to the god or goddess granting them not having access to that dimension.
hig level clerics are rare. Absolute truth... in any realm except Faerun. 17th to 30th level characters in Forgotten Realms are damn near a dime a dozen, and the spell can bring back Outsiders, IE., creatures born and native to other planes and dimensions. The only thing you can't bring back is old age and constructs, Annette should be neither.
As for the question of if the cleric will do it... Give a big enough donation to a church, they'd raise Moander for you.
