Bottom set on very scare board 25/50 PLO

[ITILTEZ]

25 50 on small euro site. I have ~$4000 and both opponents cover, the game has been playing fairly tight, the villain of this hand has made small raise in about 75% of the hands preflop, but has been playing tight postflop.

I limp from button with 3 [img]/images/graemlins/diamond.gif[/img] 3 [img]/images/graemlins/heart.gif[/img] K [img]/images/graemlins/diamond.gif[/img] T [img]/images/graemlins/heart.gif[/img] SB raises to $150 BB calls and I call.
Flop is A [img]/images/graemlins/club.gif[/img] J [img]/images/graemlins/club.gif[/img] 3 [img]/images/graemlins/spade.gif[/img] SB leads for $400 and BB folds. What is my plan? If I raise am i going to call reraise or fold.
