"The rogue’s attack deals extra damage any time her target would be denied a Dexterity bonus to AC (whether the target actually has a Dexterity bonus or not), or when the rogue flanks her target." - Player's Handbook, page 50
"Attacks
Some spell descriptions refer to attacking. All offensive combat actions, even those that don’t damage opponents are considered attacks. Attempts to turn or rebuke undead count as attacks. All spells that opponents resist with saving throws, that deal damage, or that otherwise harm or hamper subjects are attacks. Spells that summon monsters or other allies are not attacks because the spells themselves don’t harm anyone."
- Player's Handbook, page 171
If I'm reading this correctly, you can sneak attack with spells such as Entangle, Grease, Hold Person, etc. because they require saving throws or otherwise harm or hamper subjects and are thus attacks (and a Rogue's attack can deal sneak attack damage).
"Any spell that requires an attack roll and deals damage functions as a weapon in certain respects, whether the spell deals normal hit point damage, nonlethal damage, ability damage, or energy drain. Such spells can threaten critical hits, can be used in sneak attacks, and can be used with favored enemy damage bonuses." - Complete Arcane, page 85
This does not contradict the above PHB quote in that it does not say that only weaponlike spells can be used in sneak attacks.
There is a bit of an issue in determining what kind of damage would be dealt for spells that normally deal no damage. Is it untyped damage? It it untyped nonlethal damage? The only source I can find that addresses the type of damage dealt by sneak attack is a ROTG article:
"Sneak attack damage is always the same type of damage as the weapon used to make the sneak attack." - All About Sneak Attacks (Part Three)
If you can sneak with just about any spell, even if it doesn't deal damage, Arcane Trickster would be one hell of a PrC- even its area control spells like Grease would deal damage.

P.S. I am aware this makes no sense. I'm simply examining RAW.
