You didn't include an accessor in dstatenorm to fetch the NAME.

package dstatenorm;
...
sub name {
    my $self = shift @_;
    return $self->{NAME};
}

Then in your code, request the name of the state.

print $driver->alertness->name

PS: don't use prototypes especially when writing object oriented code.
