Sort by multiple headers at once?

I'm doing a database for a client, a little out of my wheelhouse, and I'm super rusty at Excel, want to make sure I'm doing it efficiently.

The key part is his client list, customer wants to be able to sort by multiple values at once. For example, he wants to know which of his clients are the longest-lasting, who orders the most often, who orders the highest value, and who fits all three of those criteria.

There's a few other fields involved, but that's the main feature he wants.
