not sure about elegance, but my two cents:

>> mylist = ['dir_0_error.dat', 'dir_120_error.dat', 'dir_30_error.dat', 'dir_330_error.dat']
>> mylist = [(int(item.split('_')[1]), item) for item in mylist]
>> mylist.sort()
>> mylist = [item for idx, item in mylist]
>> mylist

['dir_0_error.dat', 'dir_30_error.dat', 'dir_120_error.dat',
'dir_330_error.dat']
