T-SQL (SS2K8) :: Give Point And Set The Score

I've table and data as following,

CREATE TABLE [dbo].[x_SCORE](
[idx] [int] IDENTITY(-2147483648,1) NOT NULL,
[CVID] [int] NOT NULL,
[myGender] [char](1) NULL,
[whatGender] [char](1) NULL,
[point_Gender] [tinyint] NULL,

[Code] ....

So, my table and data must be as following,

This is the calculation for CVID=1449

1- myGender=M
2- whatGender=M
3- point_Gender=4
4- So, score_Gender=4

5- myBMI=23.53
6- min_BMI=20.22
7- max_BMI=30.00
8- point_BMI=3
9- myBMI is between 20.22 and 30.00
10- So, score_BMI=3

This is the calculation for CVID=1925

1- myGender=F
2- whatGender=M
3- point_Gender=4
4- So, score_Gender=0

5- myBMI=35.43
6- min_BMI=20.22
7- max_BMI=30.00
8- point_BMI=3
9- myBMI IS NOT between 20.22 and 30.00
10- So, score_BMI=0

After calculation, my data should be as following :

The variant for each row IS SAME. See as following :
