drupal_add_js weight
In what function in template.php are you adding this? A preprocess function I hope.  

Anyway, you have to set the 'group' option as outlined on the drupal_add_js page. eg.

drupal_add_js('sites/itascacg.com/themes/custom/icg/js/fixtitles.js',array('type' =&gt; 'file', 'weight' =&gt; -19, 'group' =&gt; JS_LIBRARY));
