in reply to sorting by field of a tab-delimited hash value

Something like that: 
sub GPA_sort {
    ( split /\t/, $students{ $a } )[ -1 ]
        <=>
    ( split /\t/, $students{ $b } )[ -1 ]
    }

    This looks great. But for some reason when I use this, the values of the hash are added to the hash as keys with no values. Any idea why??

    PS: I would really like to know why this is happening.
