Search Results to show types instead of complete list

At the moment my website (built on kohana) searches SOLR and it displays a list of 10 items, with pagination for upto 300 pages.
I am after the website being split into blocks (SOLR does download the type already) so that type 1 10 results is shown first with pagination, then type 2, type 3 etc. The look and feel of the search results should match what it currently is, but the blocks of different types is easier to see.
There are 3 files index.php, search.js and search.php where the search information is stored. All other facility on the search results needs to stay the same.
