It's a feature. I suggest using the the mapinfo instruction.

in ps/ps.map/do_grid.c

do_grid_numbers()

    /* round grid to multiple of 10 */
    rounded_grid = 1;
    if (PS.w.proj != PROJECTION_LL)
    {
        sprintf(num_text, "%d", PS.grid);
        len = strlen(num_text);
        while (len-- && num_text[len] == '0') rounded_grid *= 10;
        if (rounded_grid == 10) rounded_grid = 1;
    }
*

and a little later,
        sprintf(num_text, "%s", format_northing(g, rounded_grid));

and the format_northing() fn at the end of that file.

a cheap hack to disable the feature is to add a line:
  rounded_grid = 1;

at the "*" above.
