Hm... further investigations make me think there's a bug in Net::SSH::Perl or Net::SFTP.

try adding this to your code: 

my %args = (
    user     => 'user', 
    password => 'password',
    ssh_args  => [ 
        debug => 1,
        options => [
            "PreferredAuthentications 'keyboard-interactive,password,h
+ostbased,publickey'",
            ]
    ],
);

and then: 
eval { $sftp = Net::SFTP->new($host, %args) };
die "Connection failed: $!\n" if $!;
die "No SFTP object\n" unless $sftp;

my output goes like:

So when I try authenticating with an ssh-key, all works out perfectly. When I try to supply a username and a password, they seem to be ignored.. maybe we need to supply a specific value to ssh_args ?
Per default, Net::SFTP uses the username that's executing the script as SSH username...

I'll keep you informed if I find a solution...
