In addition, 'myself' is a reflexive pronoun, so it needs a pronoun to connect with, like this,
[1] I did it by myself.
Reflexive 'myself' is connected to the pronoun "I".
In your example sentence reflexive "myself" doesn't connect to anything,
[2] . . . please ask Scott or myself.
Use "me" there. It's the Standard.
Speakers will use 'myself' in that context, though. The reason is this:
Using 'myself' on its own like that allows the speaker to take focus off herself/himself, which is considered less direct because the person's name or referent (e.g., Mary, me) is not overty or directly stated. And if something is not directly stated, it's considered more polite. That's why some speakers, if not many, use 'myself' on its own. But, please remember, it's not the Standard, so use "me" instead of 'myself'.
All the best,
