the problem you're running into is that lexical ordering of numeric data != numeric ordering. If you have a mixed alpha and numeric data, you man not care if the alpha stuff is first, i.e.
asdb456 asdf490 sorts fine. Problems happen with 9jsdf 100ukel the 100ukel comes first. So if you have a mixed alpha and numeric situation, you have to either live with it or normalize the numeric data so it lexical ordering == numeric ordering, the most common way is to left-pad numeric data to a fixed-width, i.e. rather than index asb9fg, index asb0000009fg. Of course you have to know what the upper limit of any digit is for this to work...
