Dear Monks, I have a data structure like this: 

$VAR1 = {
          '1.2.3.4' => {
                              '27029' => 5,
                              '20617' => 1                            
+                                                                
                       },                                             
+                                                           
          '1.2.3.5' => {                                              
+                                                          
                              '51509' => 1,                           
+                                                               
                              '17427' => 1,                           
+                                                               
                              '63961' => 7,                           
+                                                               
                              '22331' => 1,                           
+                                                               
                              '20780' => 7                            
+                                                               
                       },                                             
+                                                          
          '1.2.3.6' => {                                              
+                                                        
                              '1500' => 3                             
+                                                             
                       },                                             
+                                                        
};

It's a HoH where nested keys are ports and values are number of connections to that port. I'm printing out the data like this: 
for my $ip ( keys %conn ) { 
    for my $port ( keys $conn{$ip} ) { 
        if ( $conn{$ip}{$port} > $max_conns ) { 
            printf "%-15s connected to TCP port %5d %9d times\n", $ip,
+ $port,
              $conn{$ip}{$port};
        }   
    }   
}

I'd like to sort the output based on the number of connections to a port, ex.: 
1.2.3.5         connected to TCP port    20780     7 times
1.2.3.4         connected to TCP port    27029     5 times
1.2.3.6         connected to TCP port     1500     3 times
...

How do I write a sort like this? (You can find the whole script here.)
