```
from typing import List, Tuple

def find_pairs(lst: List[int], target: int) -> List[Tuple[int, int]]:
    sorted_list = sorted (lst)
    pairs = []
    for a in sorted_list:
        if target - a in sorted_list:
            pair = (a, target - a)
            reverse_pair = (target - a, a)
            if pair in pairs or reverse_pair in pairs:
                continue
            pairs.append ((a, target - a))
    return pairs
```
Кстати, в вашем примере того, как должна работать программа, не хватает пары `(5, 5)`.
