> InternalSortedBag always use ascending order. We shall obey the sort order as specified
in the script.
> For example, the following script does not do the right thing if we turn off secondary
sort (which means, we will rely on InternalSortedBag to sort):
> {code}
> A = load 'input' as (a0:int);
> B = group A ALL;
> C = foreach B {
>     D = order A by a0 desc;
>     generate D;
> };
> dump C;
> {code}
> If we run it using the command line "java -Xmx512m -Dpig.exec.nosecondarykey=true -jar
pig.jar 1.pig".
> The sort order for D is ascending.
