Can an Undead Servitor use a ritual scroll?
Undead Servitor The corpse shudders, then clambers to its feet. At your direction, it shoulders your gear and lumbers after you.
Component Cost: 150 gp Market Price: 360 gp Key Skill: Arcana (no check)Level: 6 Category: Creation Time: 1 hour Duration: Permanent
You imbue a humanoid corpse of natural origin and Medium or smaller size with the ability to move under its own power and an understanding of one language of your choice. It has speed 6 and Strength 16, never tires, and obeys you at all times. The undead servitor is a noncombatant. When forced onto an active battlefield, treat the servitor as an allied minion (1 hit point, never damaged on a missed attack) with all defenses of 11. It acts just after you do and never makes attacks. You cannot have more than one undead servitor at a time from different performances of this ritual. If you attempt to create a second servitor, that ritual fails without component expenditure.

There is no minimum intelligence requirement - a brain-damaged barbarian PC can use one.
There is no requirement for magical training - any class can use a ritual scroll.
The possibility that they must be alive is a grey area, due to the existence of Vryloka, Revenant and Archlich PC's.
The need for spoken components may be more iffy - but carefully applied Magic Mouth rituals may turn the trick, as it is possible for other PC's to assist the ritual caster.
The need for instructions for the Servitor can also be bypassed with Magic Mouth - although if it understands a language it could presumably read the instructions on the scroll.
EDIT: I should probably come clean with my sinister motive; my Wizard is paranoid about dying, and doesn't trust anyone else in the party to raise him with a scroll, assuming they weren't dead themselves. By keeping a kitted-out Servitor back in his lair, he can set off a complicated contingency that results in the Servitor raising him shortly after he dies. It takes several more rituals, a specific magic item, lots of funding, and only works once before the whole thing has to be reset, but the Servitor was the lynchpin of the whole plan, as it is the only servant-type creation that persists permanently.
