[BUG] Incorrect sorting in archives with SortUpper=3

[Flint]

Steps to reproduce the bug:
1. Make SortUpper=3 in your wincmd.ini.
2. Create some subfolder named, e.g. abc\
3. In this subsolfer create two files: 123 and _123. They are sorted: _123, then 123.
4. Pack the whole subfolder into RAR or ZIP (so that the subfolder itself was in the archive). Let's name it Arch.rar.
5. Now, go into this archive, then - into the subfolder abc\ in it. We'll see that the files are sorted incorrectly: 123, then _123.

PS: I use TC 6.53 on WinXP SP2.

Confirmed, but it's strange because it only happens if you pack the whole subfolder.
