My blog has a search box. Results are displayed in reverse-chronological order. Is it possible to change this, so that results are displayed in chronological order or some other order? Alternately, is it possible to create a “sticky” page, so that a particular page will always come up as the first result?
I’m sorry but you cannot change the order of the searchbox results display. You can create a sticky post, which is for the purpose of sticking a post to the front page of your blog rather than what you suggest. http://en.support.wordpress.com/posts/post-visibility/
