Zerodha Margin Calculator Sorting is not proper

Was trying to get stocks with good margin. Zerodha provides 

link with margin details. Wanted to sort the list in descending order(10x,9x,8x,....3x), but it's not sorted properly.It's showing records in word sorting order not in number sorting order... (10x,3x,4x,.....9x).

A suggession is to make the fields only numeric inestid of x factor (i.e 10 , 9 ,8 ... no 10x,9x,8x).

And change the header to MIS Multiplier(X). CNC Multiplier(X). 

We will have this fixed.
