You actually cannot guarantee that no two values come together (for instance, all values might be the same). But you can distribute them. Here is a method using a subquery and variables:

select t.*
from (select q.*,
             (@rn := if(@v = col, @rn + 1,
                        if(@v := col, 1, 1)
                       )
             ) as rn
      from (query) q cross join
           (select @v := -1, @rn := 0) vars
      order by col
     ) t
order by rn, col;
