Custom ordering in TSQL

Question

I need to implement custom ordering for my table. For example I have a table called "TestTest" with values: a, d01, d04, d02, b . I need to select data and order them so that values with "d" will be first and rest will be sorted alphanumerical. So the result would be d01,d02,d03,a,b

Script to create and insert data:

CREATE TABLE TestTest(
Name varchar(200)
)
DELETE FROM TestTest

INSERT INTO TestTest( Name )
VALUES( 'a' )

INSERT INTO TestTest( Name )
VALUES( 'd01');

INSERT INTO TestTest( Name )
VALUES( 'd04');

INSERT INTO TestTest( Name )
VALUES( 'd02');

INSERT INTO TestTest( Name )
VALUES( 'b' );

Thx for any help ;)
