That's a rather odd query... Values in b aren't available to order by,
as they have been aggregated. There is no relation to the values in b
and the values in your result set.

You could order by "column 2" if you want to order on the results on
your aggregate:
    Select a, aggregate(b)
    from c
    group by a
    order by a,2
