You can use query_posts to sort posts by custom fields (also referred to as meta key value pairs). Assuming you just want to add the sorting to the current view's query, you can do something like this:

global $query_string;
query_posts($query_string . '&meta_key=foo&orderby=meta_value');

No you do not have to create custom fields.

You can use a plug-in like this: http://wordpress.org/extend/plugins/wp-post-sorting/

or do it by editing your category file: http://codex.wordpress.org/Alphabetizing_Posts
