Based on the fact that your hash keys are numeric, and that you depend on the output being ordered, I think you need an Array of Arrays

my $output = "";

my @AofA = (
             [
               '1;;;;;;;',
               ';;;;;;;;',
               ';;;;;;;;',
               ';;LINE;;SVC;LINE;ACCT;VIEW;'
             ],
             [
               '1;;',
               ';;;',
               ';;;',
               ';LINE;;'
             ],
             [
               '1;;;;;',
               ';;;;;;',
               ';;;LAST;;;',
               ';UPDT;SRCE;UPDT;UPDT;WORK;'
             ]
            );


foreach my $array_ref ( @AofA )
{
 $output .= $array_ref->[3];
}

print "$output\n";

output is

;;LINE;;SVC;LINE;ACCT;VIEW;;LINE;;;UPDT;SRCE;UPDT;UPDT;WORK;

If you do want a hash, then you will have to sort the hash keys to get teh output in the order you want
