Show sticky posts in selected category at the top

I would like to extract the posts that are marked as sticky and show them at the top in each category (archive.php).

When I use this function:
query_posts(array(‘post__in’=>get_option(‘sticky_posts’)));

I get sticky posts from all categories.

What can I do to extract sticky posts from only the selected category?

I need something were the current category name/ID is automatically selected.

Thanx ??
