Stupid question, but if Undead has an Int score are they considered 'Intelligent' for Turn Undead feat?

[harmor]

Medium Zombie has a an Int score of - for Int whereas a Vampire has an Int score of 14.

Turn Undead:

Calling upon higher powers, you cause undead to flee from the might of your unleashed divine energy.

Prerequisites: Channel positive energy class feature.

Benefit: You can, as a standard action, use one of your uses of channel positive energy to cause all undead within 30 feet of you to flee, as if panicked. Undead receive a Will save to negate the effect. The DC for this Will save is equal to 10 + 1/2 your cleric level + your Charisma modifier. Undead that fail their save flee for 1 minute. Intelligent undead receive a new saving throw each round to end the effect. If you use channel energy in this way, it has no other effect (it does not heal or harm nearby creatures).

Is that the difference?

Undead with a dash for Intelligence:
Skeleton
Skeleton [Template]
Zombie
Zombie [Template]

Undead with (an intelligence score):
Allip (11)
Apparition (10)*
Bhuta (12)*
Bloody Bones (12)*
Carrionstorm (2)*
Coffer Corpse (6)*
Darnoc (12)*
Deathweb (6)*
Demiurge (14)*
Devourer (19)
Ghost (10)
Ghoul (13)
Shadow, Greater (6)
Lich (22)
Mohrg (11)
Mummy (6)
Shadow, Common (6)
Skeletal Champion (9)
Smoke Haunt (8)*
Spectre (14)
Totenmaske (16)*
Vampire (14)
Wight, Common (11)
Witchfire (17)*
Wolf, Ghoul (6)*
Wolf, Dire Ghoul (6)*
Wraith (14)

So is it if its not a Skeleton/Zombie then it gets a save per round vs. the `Turn Undead` feat?

In short yes. If the have an INT score they get a save every round to end. If they have -(Nil) for an int score they just continue running for 1 minute.
