to made the attack effective, the isp should also mitm access to

The article talks about rerouting tor connections, not distributing a
trojaned tor package.
In the first case the (original) client is safe as keys are stored inside
it, in the latter where're not talking about tor. Once you trojaned a
program, any program, you haven't discovered any limits or
vulnerabilities: you've just INSERTED them.
It's funny, because this reminds me of some years ago: there was an
italian team which claims to have beaten any secure connections to home
banking sites and that https was dead. Guess how? with a trojan that
intercepts login/password. they surely got it right ;-)
It's stressed on the faq and every time you run your client: tor is not a
silver bullet for your privacy and anonymity, it has problems, but,
surely, this is not one of them.
