I tried to write it below,it can work,:)
v= """preference 10 host mx1.domain.com
preference 30 host anotherhost.domain.com
preference 20 host mx2.domain.com"""
x=v.split("\n")
li =[]
for i in x:
k = (i.split())[3]
y = (i.split())[1]
li.append((y,k))
li.sort()
print li
the output is:
[('10', 'mx1.domain.com'), ('20', 'mx2.domain.com'), ('30',
'anotherhost.domain.com')]
