Here's what I did:
import re
file = open('newrefs.txt')
text = file.readlines()
file.close()
newfile = open('sortedrefs.txt', 'w')
refs = []
pattern = re.compile('\(\d{4}\)')
for line in text:
year = pattern.search(line).group()
refs.append((year, line))
refs.sort()
for ref in refs:
newfile.write(ref[1])
newfile.close()
