I assume with the 10-day deadline on raise dead that this represents some celestial bureaucracy, and a character's soul is always going to be "free to return" within that window unless someone or something had a claim on the soul. Gods are almost always willing to turn the souls of their servants loose, because a living servant is more useful than a dead one; it's only creatures that trade in souls, use them as currency, that get greedy.
Of course, this royally sucks for Warlocks, at least those with Fiend patrons.
