S.63 applies to any sexual offence within Part I of the SOA 2003.
Think about this logically - is someone really likely to say, "Well, I'm going to break into that house over there. I'm going to attempt to rape the girl inside. I'm not going to succeed though. Let's just see how far I get before someone calls the police?" If this person attempts to rape the victim, they intend to commit rape. It therefore follows that if you enter the house with the intention of raping but you don't succeed, it might be an attempted rape BUT you have the intention to rape and therefore S.63 applies. How it ends doesn't matter - you just need the intention.
I'd guess the presumptions do apply to rape.
