jQuery Grid Plugin - jqGrid

I am checking out the tool and doco, and things looked pretty good. I integrated jquery 1.4.2 and jqGrid 3.6.5. When I attempt to load the data.. all I get in the screen is a "Loadng…" box [1]. The data comingback seems to match the expected data structure with the excpetion of order:

My code for invoking the Grid is:

%table#t2
#pager
 
:javascript
    jQuery(document).ready(function(){
      jQuery("#t2″).jqGrid({
        url:'/consumertypes.json',
        jsonreader: {cell:"", id:0, repeatitems:true},
        datatype: 'json',
        mtype: 'GET',
        colNames:['ID','Label'],
        colModel :[
          {name:'id', label:'ID', width:55},
          {name:'label', label:'Label', width:90},
        ],
        rowNum:10,
        rowList:[10,20,30],
        sortname: 'label',
        sortorder: 'desc',
        viewrecords: true,
        caption: 'Consumer Types'
      });
    });

So.. a couple of questions..

1) Are the latest versions incompatible?

2) Does the order of the data coming back matter? The doco shows numbers as strings, does that matter?

2) Am I making some other stupid user error (pebkac)?

Thanks in advance!
