Giant or Skeleton? Or both?

Yup, looks like a clear "no bonus" in this case.

Well, if the dwarf bonus would be cause of the size... why not against dragons either? Or anything else?

If it was based on size, yes, that should be the case.
But it is against Giants. They have a knack for defending against them, probably because they are more or less "natural" enemies in their home region.
They know how to dodge a Giants attack. But a Giant attack is different from a Dragon attack, or the attack of a Beholder...

Intelligent undead templates generally give the subtype augmented (base type) so a human vampire still is subject to human or humanoid targeting stuff such as an enlarge spell.

Er, I'm sure that this is wrong. The Augmented subtype is only to show that the creature might have features that are not normally available to the new type.

Augmented Subtype: A creature receives this subtype whenever something happens to change its original type. Some creatures (those with an inherited template) are born with this subtype; others acquire it when they take on an acquired template. The augmented subtype is always paired with the creature’s original type. A creature with the augmented subtype usually has the traits of its current type, but the features of its original type.

Er, I'm sure that this is wrong.

Yeah... I couldn't find anything to support it either...
