VS flight number on DL metal: awards DL TP or VS TP?

Greetings.
If I travel on a VS flight number that is a DL code share (i.e., DL metal) on a transatlantic sector (> 3000 miles), will I be awarded VS tier points (i.e., 25 tier points for X) or DL tier points (i.e., 50 tier points in X, as > 3000 miles)?
Thanks very much,
-Brad
