I’m looking for a way to sort an area in Google Sheets using script
When sorting, 2 rows should always be grouped and then sorted by column B. Can someone help me please?

I have this

COLUMN A    COLUMN B

Porsche     | 11
green       | 11
Mercedes    | 8
green       | 8
Ford        | 10
red         | 10


I want this:

Mercedes    | 8
green       | 8
Ford        | 10
red         | 10
Porsche     | 11
green       | 11
