Set Column mark sequence by X,Y direction

Recently i am trying to set the column mark sequence by x,y direction … and i m using the sorting index concept to set the column mark from minimum of x value. i feel that it’s almost achieve but i do not know what is wrong with my nodes… one of the value is mixed to minium value of x group. Hope someone can advice on my problem.
