Index selection fails in Ti build if attribute ordering in query does not match index definition

[deyles-zz]

Queries against indexed collections in Ti are failing when the ordering of attributes within queries is not the same as the index definition. Example provided below:

var collection = scule.factoryCollection('scule+dummy://test');
collection.ensureHashIndex('a,b,c');
for(var i=0; i < 1000; i++) {
   collection.save({
      a:i,
      b:i*2.
      c:i*3
   });
}
var o1 = collection.find({c:15, a:5, b:10}); // returns null
var o2 = collection.find({a:5, b:10, c:15}); // returns [{a:5, b:10, c:15}]

The above queries should be equivalent.
