Question ORDER BY Average of values in subtable

The situation is that I have two tables, one "T_Team" and one "T_Player". T_Team contains a team name and index value, and T_Player contains a foreign key representing the team index, a player name, and a score.

What I'm trying to do is create a select statement that will retrieve all the team names and order them by the average score for that team. The following obviously won't work because the nested select has no reference to the higher level table:

SELECT T.Name
FROM T_Team T
ORDER BY AVG(
SELECT P.Score
FROM T_Player P
WHERE P.FK_TeamIndex = T.Index
)

How does one get around this though?

K.

Code:
SELECT T.Name, avg(score) ascore
FROM T_Team T join T_Player P
on P.FK_TeamIndex = T.Index
group by T.name
order by ascore desc
