Taking your word for it doesn't supply actual ddl, which is what's needed to help with a solution. If this is not what you mean ...

drop table if exists table1,table2,table3,table4;
create table table1(id int,p int,points int);
create table table2 (
  pos int, id int,cp int,f1 int,f2 int,f3 int, f4 int,f5 int,f6 int,f7 int,gid int
);
create table table3(id int);
create table table4(gid int,r1 int); 
 
SELECT 
  row_number() over win as pos,
  f6, table2.id, (f7+ifnull(table1.p,0)) as cp, f1, f2, f3, f4, f5 
FROM table2
LEFT JOIN table3 ON (table2.id = table3.id)
LEFT JOIN table1 ON (table2.id = table1.id)
WHERE table2.gid = (SELECT max(gid) FROM table4 WHERE not(isnull(r1)))
WINDOW win AS (ORDER BY (f7+ifnull(table1.points,0)) desc, f1 desc, f2 desc, f3 desc, f4 desc, f5 desc) ;

... you'll need to provide usable DDL and a fuller, clearer explanation of the Order By logic you wish to add.
