yes.

Thanks, Ben! I resolved it in enother way.

I opened folder “Lib” in plugin folder and changed code in “UserList.class.php”.
in line 667 I replaced $total += get_usernumposts($user_id); on $total += get_usermeta( $user_id, 'cpoints', true );

in line 672 $total += get_usernumposts($user_id); changed on $total += get_usermeta( $user_id, 'cpoints', true );

AND in line 248 changed post, and posts on simbol of points. For example ♥

Thats all. Go to widget area of author-avatars and choose order by: Number of Posts and Sorting direction: descending.
and if need display options: show nomber of posts and bio. (Bio i changed too. Like here: http://ww.wp.xz.cn/support/topic/plugin-author-avatars-list-show-aim-web-or-similars-instead-of-bio-in-widget?replies=4 and it display number of points.)
