This is likely done to inhibit any slop that exists between the sleve and the brake post. I wouldn't think it's required, and seeing how much slop my XTs developed over the years while still functioning, I don't think your Single Digit brakes will have any trouble without those particular bolts.
First I'd suggest checking with your LBS, who probably has a box of miscelleneous bolts.
If not I'd call Avid -- in the past they've been pretty good about taking care of us with stuff like this.
If you install "plain" bolts, just make sure that once secure, the brakes don't bind.
