I wouldn't recommend it for a number of reasons:
- If the resume is reviewed by the Human Resources department before it is sent to the actual group hiring, they might not be aware of what Stack Overflow is.
- There is nothing written that says the Stack Overflow reputation is always going to have a numeric values; they might decide at one point to change the value to a label, similar to what Slashdot did.
- If you provide a number then you would also have to provide your user name, if someone browses your answers they might decide they don't like the way you answered something.
- There really isn't anywhere to put such an item on a CV.
About the only place where it might make sense would be in a personal blog that you have, but even then it might not be something that you just want out there in the open, even if you have a high score.
