используя pandas
import pandas as pd
data = ['Version1 2016,03,12 22:30', 'Version2 2016,03,29 23:00', 'Version3 2016,04,07 16:00', 'Version4 2016,02,24 15:00']
df = pd.DataFrame(data)
df = pd.concat([df, df[0].str.split(" ", n=1, expand=True)], axis=1)
df.columns = ["text","version","timestamp"]
df.timestamp = pd.to_datetime(df.timestamp, format="%Y,%m,%d %H:%M")
df.sort_values("timestamp")["text"].tolist()
вывод
['Version4 2016,02,24 15:00',
'Version1 2016,03,12 22:30',
'Version2 2016,03,29 23:00',
'Version3 2016,04,07 16:00']
