With that said then you cannot make just the scroll itself permancy then use it to make something permanent. The scroll itself must be what you want to make permanent on object/person, using it and spell, correct?
Technically...yes. Take this, for example. Your kid, when he's all growed up, wants to be an adventurer, but unfortunately for him, he's human. YUCK! Little buggar needs darkvision! So, you wanna set him up with a little present when he's off age that will give him darkvision. So, you create the scroll, and since a scroll can have multiple spells, voila!
Scroll - Permanency (includes necessary XP to make darkvision permanent), Darkvision.
Now, you leave the instructions behind for your kid...Read scroll and cast darkvision on yourself, then read scroll again and cast permanency on the darkvision on yourself. Happy B-day!
What you can't do is combine these two spells into one simple step. They will function just as if cast normally, so they have to be separate, but you can place them both on the scroll.
You
can, however, create a scroll of permanency that has only 500XP in it, which is just enough XP to make a 1st level spell, like Darkvision, permanent on someone. So, someone finds this scroll and hangs onto it until they have something to apply it to.
