When casting these spells into Scroll or Wand form, is the summoning scheme of the caster recorded? Example: If I wanted to make a wand of Summon Creatuve IV and I have the animal domain, will it always summon the IV Animal Domain summon?

If not, is it possible to script this?

When crafting, the caster's summoning scheme is not recorded.

When casting, the user's summoning scheme is used, because it requires the consumption of a reagent or the possession of a specific domain/deity/summoning tool on the user's part.

There are items out there that use specific summoning themes/schemes, right? Would it be possible to script the wands so that they -do- record the scheme used?

I personally do support that! Maybe someone will script it.

Some balance limitations may be needed, but in general I like the idea of crazy ooze-conjurers being able to craft ooze-summoning loot, or lathanderites making light-ray summon-wands, etc.
