This part of the code counts the number of times the words repeat in the text:

with open('/Users/DIGITAL/Desktop/Python/teste.txt') as f:
    ocorrencias = Counter(f.read().split())

This part is used to sort in ascending order:

with open('/Users/DIGITAL/Desktop/Python/teste.txt') as f:

    palavras = Counter( f.read().split())
print ("Ordem por número de ocorrências:",ordenar(palavras, reverse=False))

I need to know a way to save the result of this {palavras = Counter( f.read().split())} to a new txt file

Dictionaries have no ordering in Python ! The key is to convert the dictionary to a list of tuples and then sort it:

from collections import Counter

# Abre arquivo de Entrada para leitura
with open('texto.txt', 'r') as f:

    # Calcula Quantidade de cada Palavra no Arquivo
    # e retorna um dicionario
    dic = Counter( f.read().split() )

# Converte Items do Dicionario Para Lista de Tuplas
lst = list(dic.items());

# Ordena Lista de Tuplas
lst.sort( key=lambda tup: tup[1])

# Abre arquivo de Saida para gravacao
with open('saida.txt','w') as f:

    # Para cada tupla na lista
    for tup in lst:

        # Grava linha no arquivo de Saida
        f.write( tup[0] + ":" + str(tup[1]) + "\n" )
