As Bold Clone said, we don't have to follow the BBC's numbering system. Simply because that system - as a result of being overseen by a multitude of different groups and individuals over the course of 50+ years - isn't internally consistent with how it groups stories. As you said, the BBC call it a three-parter - but RTD, who was in charge of the show at the time and wrote all three episodes, calls it two seperate stories.

TARDIS wiki needs to function as an encyclopedia - it needs consistent rules. The BBC numbering system simply doesn't provide that.
