If you want the port numbers to be listed in a particular order (which is different from a numeric or string sorted order), have you tried creating a hash with the port numbers as keys and the desired ordering as values? Something like this (if this is what you want): 
# seemingly arbitrary (but "meaningful") ordering sequence of port num
+bers:
my @port_seq = qw/554 110 80 8080 22 25 21 443 53/;

# hash to deliver ordering value for each port value:
my %port_order = map { $port_seq[$_] => $_ } 0 .. $#port_seq;

# unordered array of data (port numbers):
my @ports = qw(544 554 80 80 80 80 80 53 22 22 22 22 8080 554 443 80 8
+0 25 110 143 143 110 21 22 111 110);

# print @ports in "sorted" order:
print "$_\n" for ( sort {$port_order{$a} <=> $port_order{$b}} @ports )
+;

(I'm just guessing what the order should be for port numbers that follow "554, 110, 80", since you didn't clarify that.)

You might want the "port_seq" array to be in a config file, in case you change your mind about how the ports should be ordered (or how many/which ports are being listed).
