Do you try to access a JSONP service? – Fox32 Feb 9 at 10:19

You can't. It will be evaluated as JavaScript and just vanish in the void. – Felix Kling Feb 9 at 10:21
JSON is not a scripting language, so I guess it's not possible this way. – pimvdb Feb 9 at 10:26

if you use jquery

<script type="text/javascript">
    var json_variable;
    $.getJSON('url.json', function(json){
     json_variable = json;
    });
</script>

Are you aware of the jquery getJSON api? You can use this to download json from an url. Not sure if you can embed some json directly in a script tag, though.
