I've always thought of alignment as motivations and world-view which will determine the actions someone takes, not what a person does.
So a CE person can do good things (i.e. save the orphanage) but the question is why did they choose to save the orphanage? Did they have an epiphany and felt empathy for the orphans? Did it somehow change their perspective on the world? Or did they just do it on a whim. Even if they just have a soft-spot for orphans, that doesn't necessarily mean their alignment changed, you have to look at the whole picture. Nobody fits their alignment 100% of the time.
Which brings me back to Buffy the Vampire Slayer. You have most of the Scooby gang were good aligned, even if they didn't always adhere to it. Willow for example went all apocalyptic for a while. Faith on the other hand was more neutral, sometimes doing good but having little respect or empathy for others with shifts into evil. I'd say Spike shifted from evil to neutral as well because while he was trying to be "good" it was for selfish reasons.
We aren't privy to the inner voices guiding the characters on the show, so law and chaos are a bit more difficult. I'd say Gyles was lawful and believed in rules and law even if he decided the council was not a valid authority.
Whether or not Gyles thought the order had just rules that he had to follow, I see no indication that he gave up on his basic principles. When it comes to vampires, they seem to be pretty much chaotic evil. Yes they obeyed The Master, but that seemed to be more motivated by fear of consequences than a dogmatic devotion to a proper "order" to things.
