Store text file in an array

Hello everyone
I have text file and I need to store it in an array
The lines needed to be stored is after this line

##,#02,#09,#10,#20,#36,Total

till before the last line

AVG,12.7,12.9,13.9,14.9,14.8,69.1

Then to sort the array based on the column of total in descending way ..
Note : I don't need to open the text file as excel file .. I just need to deal with the text file directly
