First of all thanks for doing this and sending in questions, now is
the time to catch GTK 2 problems.

One way would be, assuming "num" is 1, 2, 3 as you have the files
numbered, and "filename" is the filename:
gchar *str;
gchar *escaped;
escaped = g_markup_escape_text (filename, -1);
str = g_strdup_printf ("<span underline='low'>%d</span>. %s",
num, escaped);
gtk_label_set_markup (label, str);
gtk_object_set (G_OBJECT (label),
"mnemonic_keyval",
gdk_unicode_to_keyval (digit_to_unichar (num)),
NULL);
g_free (escaped);
g_free (str);
Where digit_to_unichar() is just something like:
switch (num)
{
case 0: return '0';
case 1: return '1';
...
}
probably something like "((gint)'0') + num" would work too.
I think just set_pattern ("_") might work instead of playing with
markup, that might be a lot easier.
Another option is that I think you can escape _ with __ in
set_mnemonic(), so you could write a function to go through the
filename and escape any _, that might be a better way too.
Useful docs:

http://developer.gnome.org/doc/API/2.0/glib/glib-simple-xml-subset-parser.html
There are a couple things that are kind of inconvenient here:
- mnemonic_keyval is only available as a property, there's no
corresponding function
- no digit_to_unichar() to match g_unichar_digit_value()
