Tomato is not optional so you have no choice but to put them in a chain. And 2 Peten sent to the Graveyard via Painful Choice doesn't represent what I'm talking about either. Obviously if 2 Peten are sent to the Graveyard via Painful Choice you could only activate one of them because only one could resolve successfully anyway there would only be 1 Peten left in your hand or deck to special summon. Now, I'd be interested to see the ruling on Peten and Gilfar Demon both being sent via Painful Choice and I'll pretty much guarantee you'd have to choose one or the other to activate. What I'm talking about is this:
Revival Jam is an optional effect, thus according to the rulings we currently have on optional effects it must have no other actions occurring once it has its trigger fulfilled or you can't activate the effect. Pyramid Turtle or any of the elemental searchers are not optional thus must be resolved. So in my given scenario I have to assume Revival Jam can not be triggered as the special summon of a monster is still happening when it is sent to the graveyard.
Sorry to burst your bubble, but Tomato is an optional effect.
"When this card is sent to the Graveyard as a result of battle,
you can Special Summon 1 DARK monster with an ATK of 1500 or less in face-up Attack Position from your Deck. Then shuffle your Deck."
The "you can" text is what makes this optional. You have the right to choose NOT to look for a dark monster.
"When this card is sent to the Graveyard as a result of battle,
you may select 1 Zombie-Type monster with a DEF of 2000 or less from your Deck and Special Summon it to the field in face-up Attack or Defense Position (no Tribute is required for monsters of Level 5 or more). The Deck is then shuffled. "
Pyramid Turtle is ALSO another optional effect.
Now about Revival Jam, you will still be able to activate the effect and pay the 1000 lp because it was properly destroyed (in battle) and it is not in the middle of any other card effect that is resolving. Supposing that Jam and Tomato (getting hungry now . . .) are the same attack strength and destroy each other in battle, the turn player will have the priority to place their effect on the chain before the opponent (which is SEGOC). If Jam belonged to the turn player it would be Chain Link 1, and Tomato would be Chain Link 2. I'm assuming you know how to resove chains so you can figure it out from there.
I am only confirming what others have said before me, this is the correct ruling.
