I guess you'd have to be more specific as to what kind of protein is in the tortillas. Most vegetable proteins (from veggies and grain) are not counted in the Zone. The protein is bound to the fiber and the fiber isn't digested, so much of the protein is not available. Now, if protein was added to the tortilla, you may be able to count it.
In any case, 3g of fat is one complete fat block, and you are fairly close to one block of carb (unless you have some fiber to subtract). I would count it as 1F and 1C, but if you have more than a few grams of fiber to subtract, then you might be looking at it being 1/2C.
