in thread a little problem with sorting my data

On your second one: That will group by ID, but I don't believe it will sort by ID. That is to say: You will get all the records with a certain ID together, but you won't get the ID's themselves in any particular order. (Unless values does some subtle sorting I'm not aware of.)

    I had written a line about that, but I must have deleted it by accident.

    Indeed, it groups but it doesn't sort. I had already provided a solution for sorting. If the OP also wants to sort the ids and then do something with them, he can do: 

    for ( sort <$fh> ) {
    my @fields = ...;
    ...
}
