strcoll and locale

The following program

#include <stdio.h>
#include <string.h>
#include <locale.h>

main(int argc, char * argv [])
{
if (argc > 1)
setlocale(LC_COLLATE, "ru_RU.KOI8-R");
else
setlocale(LC_COLLATE, "C");
printf("%d\n", strcoll("a-name", "aname"));
}

prints -65 if called w/o arguments and does 1 with 'em.
Trying as I could I was unable to understand that. In C locale
as well as in ru_RU.KOI8-R minus-dash is sure preceding any letter.
Could you please help me to get it ?

Using Linux 2.4.27-1-386 GNU/Linux
libc-2.3.2
