Is it possible to use suggestion to make a character read a scroll which you've written a trap on? Im new and I've been toying with the idea of a librarian sorcerer makes people read or open his traps to set them off, instead of just having a combat oriented character. I know for the explosive runes it says that "You and any characters you specifically instruct can read the protected writing without triggering the explosive runes." Does that mean suggestion wouldn't let them go off? The *can* in their is the only thing that would make me thing it would work. Would the other traps like sepia snake work?

Yes.

No, it's "instruct" as in teach. You can teach someone not to set of the Explosive Runes.

Sure. And Illusory Script can work quite nicely too, if you have a devious mind. ;)
Also: while not on the Sorcerers' spell list, Beguiling Gift could complement this basic concept quite nicely. Just make sure you have a few tricks up your sleeve for foes that can't read...
