itemid column not returning full itemid (Item Name/Number) in nlapiSearchRecord()

I've got a programatic search I'm trying to run using the following as the basis for the code:

columns = new Array();  columns[0] = new nlobjSearchColumn('itemid');  columns[1] = new nlobjSearchColumn('internalid');  columns[2] = new nlobjSearchColumn('urlcomponent');  columns[3] = new nlobjSearchColumn('categorypreferred');  columns[4] = new nlobjSearchColumn('storedisplayname');  columns[5] = new nlobjSearchColumn('displayname');  columns[6] = new nlobjSearchColumn('parent');  columns[7] = new nlobjSearchColumn('matrix');    columns[0].setSort();    filters = [     ["type","anyof","InvtPart"],     "AND",     ["isonline","is","T"],     "AND",     ["isinactive","is","F"],     "AND",     ["website","anyof","2"]  ]    results = nlapiSearchRecord('inventoryitem', null, filters, columns);

I need to be able to sort by itemid because I need to group the items together by matrix items. But, the results that are returned in the itemid column via nlapiSearchRecord are not the same ones I get when I just execute the search in Netsuite. When I run the search in Netsuite, I can see an itemid like this:
