rewrite rule not working

Hi,
I’m adding some rewrite_rules to provide more SEO friendly urls for my plugin page.
I’m trying to match an url like this:
https://mysite.com/2-bedrooms/3-bathrooms/mycity/2.html
that means the user is looking for a house with 2 beds, 3 baths, placed on mycity and he is requesting the page 2. This url is then translated to a regular querystring-based url.
Here is my code to add my rules:

function insert_rewrite_rules( $rules ) {
	$newrules = array();
	$page_name = 'mypage';

        //basic rule
	$newrules['(' . $page_name . ')$'] = 'index.php?pagename=$matches[1]';

	//search by id
	$newrules['(' . $page_name . ')/(\d+)$'] = 'index.php?pagename=$matches[1]&id=$matches[2]&search=1';

	//url with page included
	$newrules[(mypage)(/(\w+)-bedrooms)*(/(\w+)-bathrooms)*/([^.]+)/(\d+).html$'] = 'index.php?pagename=$matches[1]&bedrooms=$matches[3]&bathrooms=$matches[5]&query=$matches[6]&page=$matches[7]';

        //url with no page
$newrules[(mypage)(/(\w+)-bedrooms)*(/(\w+)-bathrooms)*(/([^.]+))*$'] = 'index.php?pagename=$matches[1]&bedrooms=$matches[3]&bathrooms=$matches[5]&query=$matches[7]';
	return $newrules + $rules;
}
add_filter( 'rewrite_rules_array','insert_rewrite_rules' );

The rules are well saved, this is not the problem.
But redirection is not working at all. I’m able to match the url without the page (https://mysite.com/2-bedrooms/3-bathrooms/mycity), but when I add the “/2.html” wp doesn’t understand it and redirect me to https://mypage.com/2/, then this url is interpreted applying the rule of “search by id”, mentioned above.
I recently moved to wp version 3.4.1, in version 2.9.2 it worked just fine.

All I need is a regex to match with the above given url, including the current page.
Please, give me some hints.
Thanks in advance
