Absolute configuration

Sorry. This might seem like a very stupid question, but when assigning absolute configuration for glyceraldehyde, why is it that CHO gets priority over  HOCH2 ?

The CHO carbon has two bonds to oxygen and one bond to hydrogen. The HOCH2 carbon has two bonds to hydrogen and only one bond to oxygen. Since the CHO has more bonds to an element of higher atomic number, it has priority.
