It was due to the first-person Temple Rundowns Season 3 is well-known for.
The Comet-Embroidered Battle Flag of William the Conqueror, The Much-Heralded Helmet of Sir Gawain and The War Fan of the 47 Ronin used an "original" rundown, indicating Production Day 1 and making them Episodes 81-83. The Bifocal Monocle of One-Eyed Jack was the same day, but last that day, Episode 84.
Then, on Production Day 2 [Episodes 85-88] the producers decided to edit the rooms of the "original" rundown to make "personalized" rundowns that feature the artifact of the day. Renegade Pancake discovered The Thornwood Gavel of Judge Roy Bean was first of the four episodes that day, making it Episode 85. The Lion-Headed Bracelet of Chandragupta was second, making it Episode 86, since those two episodes had the only "personalized" rundowns in the season but the Thornwood Gavel came first. The Secret Map of the Bandit Queen was third that day, Episode 87 , as its rundown was the one the producers settled on to use for the rest of the season. In fact, its rundown was even used in The Lion-Slashed Jacket of Sacagawea, the final episode that day and Episode 88. The rest of Season 3's episode order, however, has yet to be determined.
