Sort Title Requires Zero Padding When Using Single & Double Digit Sort Titles

I uncovered this issue while working with the series Mortal Kombat. I gave Mortal Kombat X the Sort Title "Mortal Kombat 10". With this sort title, It was positioned between Mortal Kombat 1 and Mortal Kombat 2 on my game list. To correct this, I had to zero pad my sort titles, changing to Mortal Kombat 01 and Mortal Kombat 02.

Not sure if this is by design, but it wasn't intuitive.
