Should an AI score decide an academic misconduct case?
No, and the clearest statement of that comes from the vendors: Turnitin states its AI indicator is not intended as the sole basis for an academic misconduct finding.

A misconduct finding is a conclusion about what a person did. A detection score is a measurement of how predictable a document is. Nothing in the second gets you to the first on its own, which is why every serious policy treats the score as a trigger for a process rather than the outcome of one.
The practical problem is that the score arrives looking like a conclusion. A percentage carries an air of precision that the underlying measurement does not support, and the number is usually the only element of the report anyone reads. Whether it appears at all depends on a threshold the vendor chose and the accused is rarely shown.
What can carry weight is evidence about the work: drafts and version history, notes and sources, the ability to discuss the argument and explain choices made in it. That evidence answers the actual question, and it also answers contract cheating, which no detector sees at all.
None of this means a score is useless. It is a reasonable prompt to look more closely at a piece of work. It is simply not a finding, and treating it as one is the specific procedural failure most appeals turn on.
When this answer changes
It would change if a detector published a false positive rate for the population and text type in question, at the threshold in use, with independent verification. That would make the score a quantified piece of evidence rather than an unquantified one. Nothing on the market currently offers it.
It does not change with a higher score. A 90% figure is a stronger version of the same kind of evidence, not a different kind, and the mechanism producing it is the one that flags formulaic and second-language writing.

- Is there a safe percentage? — There is not, and the numbers circulating as one have no published source.
