grep

update: Okay how about 

@results = grep( /^$key/, @raw_data );

where key is the number your looking for. Sure you could do more fancy things like munge the array into a hash or DBFile but grep should suffice. All the matching records will be in results, then just roll through those to output the data you want: 

foreach( @results ) {
    $record = $_;
     # strip the beginning key
    $record =~ s/^\d+//;
    print $record;
}
