I thought about that.. but consider, Combat Reflexes makes you immune to Garrote?
When you said "Combat Reflexes", did you mean "Uncanny dodge"? Because I'm not seeing how Combat Reflexes would protect the target, given the suggested rules.
Assuming you meant Uncanny Dodge: well, yeah, it'd make you immune to garrote. Sounds reasonable. It *should* be difficult to strangle canny rogues and jumpy barbarians.
I understand that a garrote is a deadly weapon, but man, so is a sword. Seems like if you want any hope of keeping the weapon balanced and usable (from a flow-of-play perspective), you need to keep it as simple as possible.
Heck, in 3.0 they even de-mystified the katana, favored Uber weapon of gamers since Highlander came out.

I humbly suggest you keep the garrote grounded. It's a neat way to silence an unsuspecting foe, but it is *not* a reasonable weapon for combat.
More suggested rules:
Two-handed.
Can not be used to threaten/can not be used during an AoO.
Can only be used on a person denied their Dex bonus to AC.
Attacking with one provokes an AoO, and if attacked is damaged by AoO the attack is stopped.
If target hit by garrote, target is considered Grappled and attacker and target are grappling.
Target is unable to speak or vocalize.
If attacker attempts to Pin, Garrote gives +4 to grapple checks.
If attacker successfully pins target, target must make Constitution checks as if drowning. A failed constitution check has normal results from drowning (fail once = 0 hp and unconscious). Attacker may release target at this stage, or maintain pin. If attacker maintains pin, the next round target drops to -1 and is dying. If pin maintained the next round target dies.

Drowning
Any character can hold her breath for a number of rounds equal to twice her Constitution score. After this period of time, the character must make a DC 10 Constitution check every round in order to continue holding her breath. Each round, the DC increases by 1.
When the character finally fails her Constitution check, she begins to drown. In the first round, she falls unconscious (0 hp). In the following round, she drops to –1 hit points and is dying. In the third round, she drowns.
