In theory the idea is that a parameter is an attribute of the thing, so a user parameter is an attribute of the user part, while the URI parameter is an attribute of the whole URI. So originally it made sense that the TEL URI parameters be SIP user part ones, because they were attributes of the number itself, not of a SIP URI. There was also some concern about namespace collision of parameter names, if the two types of URI's just happened to define the same param name with different meaning.
