Random..er..Random Frame

This isnt simply just a random frame question :wink:

My simple script is as follows,
[AS]if (whatever) {
_root.somemovieclip.gotoAndStop(random(1+10));
[/AS]
It jumps into a movie clip and goes to a random frame between 1 and 10.

What I need it to do, is (for example) go into that movie clip and play either frame 3 6 or 9. Disregarding every other frame not specified.

Somebody pleeease help me on this one, Iā€™m so close to getting what I need to do done :crazy:

Thanks!
