Here is a short Python program.

```python
scores = [7, 9, 5, 7]
limit = 7
peak = 8
limit = len(scores) % 3
for elem in scores:
    peak += elem
    limit = limit + 6
codes = scores
codes[0] = 13
shift = 5

def bump(q):
    return q + shift

shift = 11
scores.append(bump(6))

def boost(val):
    peak = val * 2 + 1
    return peak + 1

bonus = boost(7)
scores.append(peak + bonus)
for i in range(1, 5):
    scores.append(i)
tally = scores
offset = peak - 39
weight = offset % 6
scores.append(weight)

def tally_up(v, m=[]):
    m.append(v)
    return len(m) + v

extra = tally_up(6)
value = tally_up(6)
scores.append(value)
scores.append(limit * 2)
scores.append(peak)
```

After this program runs, what is the value of `scores`? Work through it carefully, then give the final answer on its own last line as `ANSWER: <python literal>`.

To find the final value of `scores`, let's trace the execution step-by-step:

1.  **Initialization:**
    `scores = [7, 9, 5, 7]`
    `limit = 7`
    `peak = 8`

2.  **Updating `limit` and `peak`:**
    `limit = len(scores) % 3` $\rightarrow$ `4 % 3 = 1`
    Loop through `scores` ([7, 9, 5, 7]):
    - elem 7: `peak = 8 + 7 = 15`, `limit = 1 + 6 = 7`
    - elem 9: `peak = 15 + 9 = 24`, `limit = 7 + 6 = 13`
    - elem 5: `peak = 24 + 5 = 29`, `limit = 13 + 6 = 19`
    - elem 7: `peak = 29 + 7 = 36`, `limit = 19 + 6 = 25`
    Current state: `scores = [7, 9, 5, 7]`, `peak = 36`, `limit = 25`.

3.  **Modifying `scores` via `codes`:**
    `codes = scores` (Reference to the same list)
    `codes[0] = 13` $\rightarrow$ `scores` is now `[13, 9, 5, 7]`

4.  **The `bump` function and append:**
    `shift = 5`
    `def bump(q): return q + shift`
    `shift = 11`
    `scores.append(bump(6))` $\rightarrow$ `6 + 11 = 17`.
    `scores` is now `[13, 9, 5, 7, 17]`

5.  **The `boost` function and append:**
    `def boost(val): peak = val * 2 + 1; return peak + 1`
    `bonus = boost(7)` $\rightarrow$ Local `peak` is $7 \times 2 + 1 = 15$. Returns $15 + 1 = 16$.
    `scores.append(peak + bonus)` $\rightarrow$ Global `peak` is 36. $36 + 16 = 52$.
    `scores` is now `[13, 9, 5, 7, 17, 52]`

6.  **Range loop append:**
    `for i in range(1, 5): scores.append(i)` $\rightarrow$ Appends 1, 2, 3, 4.
    `scores` is now `[13, 9, 5, 7, 17, 52, 1, 2, 3, 4]`

7.  **Calculating `weight` and append:**
    `tally = scores`
    `offset = peak - 39` $\rightarrow$ $36 - 39 = -3$
    `weight = offset % 6` $\rightarrow$ $-3 \pmod 6 = 3$
    `scores.append(weight)` $\rightarrow$ `scores` is now `[13, 9, 5, 7, 17, 52, 1, 2, 3, 4, 3]`

8.  **The `tally_up` function (Mutable Default Argument):**
    `def tally_up(v, m=[]): m.append(v); return len(m) + v`
    - `extra = tally_up(6)`: `m` becomes `[6]`. Returns `1 + 6 = 7`.
    - `value = tally_up(6)`: `m` becomes `[6, 6]`. Returns `2 + 6 = 8`.
    `scores.append(value)` $\rightarrow$ `scores` is now `[13, 9, 5, 7, 17, 52, 1, 2, 3, 4, 3, 8]`

9.  **Final appends:**
    `scores.append(limit * 2)` $\rightarrow$ $25 \times 2 = 50$.
    `scores.append(peak)` $\rightarrow$ 36.

Final list: `[13, 9, 5, 7, 17, 52, 1, 2, 3, 4, 3, 8, 50, 36]`
