Item Creation Feats, including Scribe Scroll, are not allowed in PFS. All magic items simply spring into existence randomly, (not kidding) or are occasionally unique oddities. Said Wizard NPC likewise does not have Scribe Scroll, so can not just make a scroll for you. Being a new, uncommon spell doesn't change that.
PFS limits what you can buy, or rather what is available to be bought, though it is notably a very artificial way. In Core, as far as I understand it, those spells simply do not exist to your character until that character finds them. Its pretty clear for Wizards how that works. Not so much for everyone else.
As to the Spellbook on Chronicle Sheets, Absolutely Not!!! Its only good for about 3 classes, 1 in Core, and that is something that should be written in when it applies, and signed off. Plenty of scenarios have multiple spellbooks, too much possibility for error, and not to mention APs/Modules, and I need my extra room for trophies and other notes.
