How to find <script> elements with particular value of "type" attribute?

Assuming the following script tag in a random HTML document:

<script id="target" type="store">
    //random JavaScript code
    function foo(){
       alert("foo");
    }
    foo();
</script>

can anybody explain why the following expression doesn't find all elements of script with value store for their type attribute.

var sel = $('#target script[type="store"]');
