如何对反向排序的红宝石数组应用二级排序？

Question

I have a ruby array in the format of [["Anna",70],["Billy",90],["Billy",100]] ...

I know I can apply secondary sort using the following

sort_by{ |o| [o.name, o.score]}

However I want to sort first on Name asc and then sort on Score but descending. How could I achieve this?

Thanks
