It got mine relatively recently. I remember it took about 15 minutes after I reached 500. Either the system takes a little while to recognize the change, or I reached 501 in that time.
Note that you can't vote on comments over 24 hours old or replies to yourself, so don't use those to check your ability.

Edit: Maybe it takes more than 500, or some time. I don't have down arrows yet.
