Converting parts of a list to int for sorting

[menator01]

I've been struggling with this for a couple of days now
I'm trying to pull a list from a text file in the format below
convert the numbers to int and sort by the numbers and not the str.
I can pull the numbers only and get it to work but when trying to put them back in
I get that it has to be a string. Any help would be great.
The goal is to pull the lines of text sort by the number then write them back to the text file.

Thanks

# text file list ['13,pops','15,bubble','150,nano','33,party','pokey']

def getIt():
    lst = []
    with open("scores.txt", "r")as file:
        data = file.read().splitlines()



    newlst = data.copy()
  
    print(sorted(newlst, key=lambda x: int(x[0].split(",")[0])))

    
##    conv = []   
##
##    for info in data:
##        conv.append(int(info.split(",")[0]))
##
##    print(sorted(conv, reverse = True))
##       
##    print(data)
    
#newdata = data.copy()



getIt()
