Rank a list of scores with "skips"

T-SQL (40)

SELECT RANK()OVER(ORDER BY B DESC)
FROM @

Assume @ is a table containing the scores as rows.

J (7 6)

EDIT: Oh, wait! It doesn't need to be a function!

>:i.~y

Thank god for i.~...

>:@:i.~

Or as a named function (3 chars more, but not functionally different):

f=:>:@:i.~

Run tests:

   f=:>:@:i.~
   f 10 10  6  6  4  0
1 1 3 3 5 6
   f 10  9  8
1 2 3
   f 0  0  0
1 1 1
   f 16 15 15 12 11 11 10  9  9  9  8  2  2  2  0
1 2 2 4 5 5 7 8 8 8 11 12 12 12 15

Python (33 characters)

lambda x:[1+x.index(i)for i in x]

Functionally the same as my J answer.
