The documentation isn't very friendly, I trying this way, but I am getting a lot of XML instead of just the "999": 
...
my $t= XML::Twig->new( twig_handlers => 
                           { 'CustDetails' => sub { $_->first_child('C
+ustomerId')->text(), } }
                       )
                  ->parse($test_xml);
warn Dumper $t;
