I'm trying to sort a table I've populated by numerical order, but for some reason it's sorting 'alphapetically' (if that makes sense.)

For example, a set of five numbers:

7, 10, 13, 2, 3 will sort as 10, 13, 2, 3, 7.
12, 1, 8, 5, 7 will sort as 1, 12, 5, 7, 8
5, 11, 4, 13, 3 will sort as 11, 13, 3, 4, 5

etc. etc... 'alphabetically' in that the numbers are being sorted by their first digit across the board, then the second, so that an 11 would indeed come before 3 based on the fact that it 'started' with a "1".

In trying to sort it out, this sample code works just fine for me:

1
2
3

t = { 2,5,12,10,4 }
table.sort(t)
print(table.concat(t, ", "))

Lua is typeless, but there are times where things need to be typed.

Try this:

1	table.sort(t, function(a,b) return tonumber(a) < tonumber(b) end)

Thank you kindly both! Forcing a numeric comparison seemed to do the trick. (There was indeed an earlier table from which this one was built with quotes, but it seemed to need them at the time.)
