Scribing a scroll with an enhanced Spell-Like Ability

Following up on my previous question regarding the scribing of Spell-Like Abilities, I’d like to know how feats that affect the SLA, such as Intensified SLA, Quicken SLA, etc., affect the scribing. Unlike actual Metamagic feats, these don’t affect the "spell level" of the SLA, they’re simply usable 3 times per day.

For instance, would a quickened 1st level SLA count as 1st or 5th level for the purposes of scribing (and therefore, the gold cost)?
