T-SQL (SS2K8) :: Group By And Order By - Location Starting With A And B

I am having below schema.

CREATE TABLE #Turnover (
location varchar(50),
Total int
)

insert into #Turnover (location,Total) values('A', 500)
insert into #Turnover (location,Total) values('AB', 200)
insert into #Turnover (location,Total) values('ABC', 100)
insert into #Turnover (location,Total) values('BA', 100)
insert into #Turnover (location,Total) values('BAC', 500)
insert into #Turnover (location,Total) values('BAM', 100)

Now i want output order by total but same time i want to create two groups. i.e. location starting with A and order by total and after locations starting with B and order by total.
