using jQuery with Jekyll site hosted on Github pages

I have a simpled Jekyll blog hosted on github pages and I have included jQuery and a tablesorter plugin but come across error and to all my knowledge this error is caused by not having jQuery loaded in the correct order. my image below shows the code is in the right order.. so my question is simply is it being stopped by Github itself somehow?

and if so how?

edit: for completion/clarity here is the exact code:

<script type="text/javascript" src="/js/jquery.min.js" ></script>

<script type="text/javscript" src="/js/jquery.tablesorter.min.js" ></script>  

<script type="text/javascript">$(document).ready(function() { 
 if(jQuery("table.tablesorter").length > 0)
   {  
    $.tablesorter.defaults.widgets = ['zebra']; }
   }
 );
