Drupal Add Javascript type=text/javascript

I am trying to add javascript to my page and use type="text/javascript" however when I include the following it just encloses it in script tags. How can I fix this? Also, how can I add the type="text/javascript to external files (see the second example)

drupal_add_js("$(document).ready(function() {
    // Infinite Ajax Scroll configuration
    jQuery.ias({
        container : '#itemcontainer',
        item: '.dealstable',
        pagination: '.nav',
        next: '.nav a',
    });
    });",'inline');

Here is the second example:

drupal_add_js('http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js','external');

UPDATE: As suggested by the comments I tried the following:

$js = "(function($) {
    jQuery.ias({
        container : '#itemcontainer',
        item: '.dealstable',
        pagination: '.nav',
        next: '.nav a',
    });
    };
})
(jQuery)";
drupal_add_js($js, array('type' => 'inline','scope'=>'footer'));

But that resulted in the following HTML:

<script>(function($) {
    jQuery.ias({
        container : '#itemcontainer',
        item: '.dealstable',
        pagination: '.nav',
        next: '.nav a',
    });
    };
})
(jQuery)</script>
