It seems you want to sort the list numerically. In that case, use 
int(SortedServers[0]) as the key. Sorting by string values will sort the 
list lexicographically.

You should read the Python tutorial, specifically the sections about 
strings. Then, read the sections on lists and sequences.

In short: Don't care about the "u'" prefix, that's just fine.
