Why doesn't my alphabetical sorting algorithm work?

I made this algorithm in Python to sort a list of names alphabetically and I can't figure out why it doesn't work properly when given this list:

for a in range(0,len(V)):
    for b in range(a,len(V)):
        equal=True
        for N in range(0,min(len(V[a]),len(V[b]))):
            if ord(V[b][N])<ord(V[a][N]):
                V[b],V[a]=V[a],V[b]
                equal=False
                break
        if equal==True and len(V[a])>len(V[b]):
            V[b],V[a]=V[a],V[b]
print(V)
