Spliting Single Row Into Multiple Rows

I have a table that contains many columns in a single row and I'd like to split the table so that it has fewer column values and more rows.
My table structure is:
create table #scoresheet
(Decisions varchar(10), DNumericalValue int, DVI varchar(10), DComments nvarchar(255),
Competence varchar(10), CNumericalValue int, CVI varchar(10), CComments nvarchar(255),
Equipment varchar(10), ENumericalValue int, EVI varchar(10), EComments nvarchar(255));
I would like to have three rows with four columns.
What I've done so far is create a stored procedure that uses a table variable:
create procedure sp_splitsinglerow as

declare @Scoresheet_rows_table_var table (
ReviewArea varchar(25),
NumericalValue int,
VI varchar(10),
Comments nvarchar(255));
insert into @Scoresheet_rows_table_var
(ReviewArea, NumericalValue, VI, Comments)
select Decisions, DNumericalValue, DVI, DComments
from #scoresheet

The trouble with this approach is that I have to explicitly name the columns that I insert into the table variable. What I'd really like to be able to is have a loop construct and select the first 4 columns the first time, the second 4 the next time and the last 4 the third time.

Any ideas on how to achieve that?

BTW, I have resolved this issue by suggesting to the Developers that they change the structure of the original table, but I'd still like to know if there is another solution. :)
