I'll assume that "sort them by the 2nd two right digits" means sorting by
the 6th and 7th digits from the left.
Insert 3 columns to the left of you data (Your data will then be in col D)
In new col A row 1 use this formula to extract the 6th & 7th digits
In new col B row 1 use the formula to extract the 5th & 5th digits
Finally, in cell C1 use the formula to get the first 3 digits
Copy those formulas down, then you can sort the whole mess on the 1st 3
