A workaround could be
with emp_1 as
  select ename,sal,deptno,deptno dep_dummy,empno --"or whatever column wanted..
  from emp
SELECT ename,DESCRIPTION,VALUE
from
     select *
     from emp_1
     UNPIVOT
          VALUE FOR DESCRIPTION IN
              (sal AS 'salary', deptno AS 'dept')
order by dep_dummy,empno,description; --"and other columns..
