A double-jump is still a jump. You wouldn't say "I opened 1NT and partner quadruple-jumped to 6NT", you would just say "jumped". I agree 3H is a weak jump.

While I think my regular partners would take it as a splinter, as per my original post on this hand, an Internet search suggests that this is not the most common meaning. For example (emphasis mine):
