Sort one column based on values in another column?

I need some help setting up a spreadsheet for a sports tournament.

In cells A1 thru A10, I have a list of schools, sorted alphabetically. In cells B1 thru B10 I have a abbreviation for the school. In C1 thru C10 I have each team's score.

Beneath this list, I want to create a similar list sorted by score (from highest to lowest), rather than sorted alphabetically. I can figure out how to sort the score column, but cannot figure out how to have the corresponding school and abbreviation be matched up with each score.

I would truly appreciate any help. Thanks in advance!

Row one should be TITLES for the columns, not data. Then select the entire data table including the Titles and do a custom sort. If you sort by score, the data in the corresponding rows will move with the score
