Given an SQL query like

 select
   col1,
   col2,
   col3,
   sum(col4) over (partition by col1 order by col2, col3) as cumulative_sum
 from table1
 order by col1, col2, col3;

 select
  col1,
  col2,
  col3,
  sum(col4) over (partition by col1 order by col2, col3) as cumulative_sum
 from table1
 order by col1, cumulative_sum;

which order by clause in the end would you prefer and why?
