Refatorando sua classe:

class Mandato(models.Model):
    MANDATO_CHOICES = (
        ('1', 'Presidente'),
        ('2', 'Vice-Presidente'),
        ('3', 'Diretor')
    )
    titular = models.ForeignKey(Pessoas, blank=True, null=True, related_name='titular')
    atribuicao = models.CharField('Atribuição', max_length=1, choices=MANDATO_CHOICES)

Assim consegue uma consulta ordenado pelo Presidente, Vice e Diretor:

Mandato.objects.all().order_by('atribuicao')

Caso queria de baixo para cima:

Mandato.objects.all().order_by('-atribuicao')
