If you are only limiting this to 10 entries(Record limit).

I think it's readable to check first if array count is less that your record limit then do the addObject.
but if array count is equal to the record limit check the last value on the score array and compare to the current score(*just make sure that values in your list is in descending order) and if its greater than the last value on score array use loop to find the appropriate index to add it the remove the last object.
