I'm actually seeing a flop often with this hand even out of position at 2PLO because given that everyone else limp/called it seems like the table you were at is full of calling stations that will pay you off with things like lesser flushes, bottom two pair, or trips against your boats.
I'm curious about your reasoning for raising this flop though. cjatud2012 covered it pretty well; it doesn't work as a value bet and is too small to be an effective semi-bluff. If it was to induce him to check the turn over to you so you could see a river card cheaply it worked well... but for any other reason I either fold, smooth call, or raise pot.
As played, I'm almost never calling this river with TPTK, ESPECIALLY in full ring PLO. The only thing you beat is basically complete air. There are so many combinations in villain's extremely wide range that have you beat on the river: two straight combinations, any two pair, any set.
If villain is actually pot-size bluffing
like this out of position often, just wait for a good spot and watch the chips see-saw back over to you.
