### 1. ### Break Down the Problem
We need to determine the sum of scores ($ \Sigma X $) given the mean ($ M = 12 $) of a sample of size $ n = 5 $.

### 2. ### Relevant Concepts
The mean is calculated using the formula:
$$
M = \frac{\Sigma X}{n}
$$
where:
- $ M $ is the mean,
- $ \Sigma X $ is the sum of the scores, and
- $ n $ is the number of scores.

### 3. ### Analysis and Detail
To find $ \Sigma X $, we can rearrange the formula for the mean:
$$
\Sigma X = M \times n
$$
Substituting the values:
$$
\Sigma X = 12 \times 5
$$
Calculating the sum:
$$
\Sigma X = 60
$$

### 4. ### Verify and Summarize
The calculations have been verified through the rearranged formula, confirming that the sum of scores for the given sample is $ 60 $.

### Final Answer
The value of $ \Sigma X $ for this sample is $ 60 $.
