EDIT: Someone recently contacted me wanting to see my version of this code. So I've created a Gist at https://gist.github.com/seezee/606b015926643d861918407a31f04756.

Line 10 overrides a Wordpress global. Not only is that bad, but I'm also not even sure if it's necessary. Your code seems to work fine without it.

You should also consider using WP_Query instead of query_posts (line 79). Hit me up if you want to see my code for implementing this.
