Transfer Order Status pendingFulfillment

I am trying to loop through all the Pending Fulfillment Transfer Orders.  Every time I add the status filter I get zero results.  I've tried it a number of ways but every time I end up with no records returned.  I know there is records out there from a saved search I am running.  What am I doing wrong with the status filter?

function test(){      var recordType = ["TrnfrOrd"];      // Define search filters      var f = new Array();      f[0] = new nlobjSearchFilter ('type', null, 'anyof', recordType);       f[1] = new nlobjSearchFilter ('item', null, 'anyof', 2290966);       f[2] = new nlobjSearchFilter ('mainline', null, 'is', 'F');       f[3] = new nlobjSearchFilter ('status', null, 'anyof', 'pendingFulfillment');      // Define search columns      var c = new Array();      c[0] = new nlobjSearchColumn('entity');      c[1] = new nlobjSearchColumn('tranid');      c[2] = new nlobjSearchColumn('status');      // Search for child records      var r = nlapiSearchRecord('transaction', null, f, c);        if (r==null){          //return true;          alert('not found');      }else{          //return false;          alert(r.length);          for (var i = 1; i < r.length; i++){              alert("|"+
