I have a data file of 90 characters in each record. I want to sort the file taking in the values from 5th char to the 11th char. The problem is the fields are not separated by space or any delimiter. i have only the character positions. how do i do it ? record will look like this

2005123459080........................678
2005123349080........................678

etc. i want to take in the 6 digits from 5-11th and sort.
