scheduling a future post does not cause the category count to increment when the post becomes published (because the post date passed).
I was testing some code, but when I went through the normal WP Admin GUI and sheduled a post for 2 minutes time, the 2 minutes came and went, the post appeared, but the catagory count remained the same.
I notice that the WP Cron uses publish_future_post as the action, and this action is hooked to wp_publish_post in default-filters.php. The wp_publish_post funtion (in post.php) DOES NOT make any attempt to update the catgegory count in any way.
Looking back at version 2.2x I notice that it does indeed call other funtions that handle this, but the 2.3x version of this funtion merely updates the post_status field in posts and nothing more.
Can I confirm that this is a bug, and how do I report it for further investigation?
