that the planet's orbit be stable over thousands of years
Very low thousands is plenty if the timing is right. If anything say a few thousand years pre-Copernicus contained astronomical accounts that deviated wildly from what we "know" today, we'd put it in the same category as the artwork and accounts of the flat earth resting on the back of a giant turtle.
If you read this paper, you see they settled on a moon the same mass as Kalgash but with the density of Saturn! How could such a system possibly arise?
Gas Dwarfs?

As for the how, with 6 suns dancing around, you've got plenty of candidates to provide the required components, and lots of opportunity for freak events, collisions, etc.
Honestly, I think, after you add in 'freak occurrences' we'll eventually find some pretty spectacularly improbable planets.
