not expected bubble sort issue in python

I have a problem with this code, bubble sort is not working properly.

numero = raw_input('Ingrese los numeros a ordenar:')
numeros = []

while numero != '': #hit enter to finish the number input
    numeros.append(numero)
    numero = raw_input()

def burbuja(temporal):
    tamanio = len(temporal) -1
    ordenado = False
    while not ordenado:
        ordenado = True
        for i in range(tamanio):
            if temporal[i] > temporal[i+1]:
                ordenado = False
                temporal[i], temporal[i+1] = temporal[i+1], temporal[i]

burbuja(numeros)
print 'Los numeros ordenados son:', numeros

The problem is when I insert numbers like this

'22', '13, '2', '4'

My expected result is

'2', '4', '13', '22'

But I get:

'13', '2' ,'22', '4'

I hope you can help me to resolve my problem

Thank you :)
