    Please remark that the result of _PREVIOUSLY_ is already wrong if we assume 
that the ordering is global. Indeed the global ordering on 
`outE('created').values('weight').inV()` should yield 
{label=software,id=5,lang=java,name=ripple}

> Given the semantics of order()/aggregate()/dedup(), this should work

> test cases to ensure expected behavior.
