Obviously the confusion goes on due to a lack of definition by Konami (which should have come when the whole issue of priority was introduced) I don't blame ANYONE for having confusion on this issue, even the people who are seemingly the most "in the know" often have misconceptions concerning this issue.
I'll reference some responses on a discussion on the L3 list (which IS an official source and every bit as official as the standard judge's list btw) .........

QUESTION:
Player A activated
The Warrior Returning Alive and got back Black Luster
Soldier - Envoy of the Beggining for the graveyard.
Player B activated
Mind Crush in response to the
Black Luster Soldier - Envoy of
the Beggining being put in Player A's hand, calling Black Luster Solder - EOTB.
So my question is, are you allowed to respond to a movement like adding a card
to a hand? Also does Plaer A have Priority to summon BLS - EOTB before Player B
activates
Mind Crush?
ANSWERS:
1. Yes you can respond.
2. No the player doesn't have priority to Special Summon his monster.

So in your example is Player A's Main Phase, so he starts with the
Priority (it is his turn after all).
He Summons
Tsukuyomi. Its trigger effects starts a chain. (After a
Summon player A would normally retain priority to activate an Ignition
Effect or Spell Speed 2 Spell or Trap, but
Tsukuyomi's Trigger Effect
must start a chain).
He targets
Jinzo. The opponent may chain an effect, but does not. The
turn player may chain an effect, but does not.
Jinzo is flipped face-down.
Priority is now passed to Player B.
Player B activates "
Call of the Haunted". Neither player chain anything,
and Player B finishes his Special Summon.
Priority is passed pack to Player A. He Flip Summons
Jinzo. Since he
just performed a Summon, he retains priority only to activate an
Ignition or Spell Speed 2 Spell or Trap. If he decides not to activate
one of those kind of effects - Priority passes to Player B.
Do you see how priority is passed back-and-forth between the players,
with the only hiccup being when the turn player performs a Summon.
It's not as complicated as everyone makes it out to be - and there is
only 1 kind of priority.
