How to use alternative font for intermission text screen?

When I replaced the original STCFN Smallfont to the custom font, which has two letters with different size/color than the others, any ZDoom-related source ports automatically changed the color of the entire STCFN font to much darker one than originally designed. To avoid this issue, while I preserved the new STCFN lumps, I decided to use FONTDEFS to define the other font, designed to be used with ZDoom. I also defined the secondary font, in order to use the two letters I mentioned. So the FONTDEFS is now looks like this:

Quote

Smallfont
{
    Template DNSMR%03d
}

Secondfont
{
    A DAISY091
    B DAISY093
    DONTTRANSLATE
}

The problem is that I can't use the "Secondfont" for the intermission text screen with ZMAPINFO. AFAIK, there are no commands to change the font of text screen from either ZMAPINFO or LANGUAGE. I looked around, and found the tutorial that uses ACS to demonstrate the text screen with custom font: 

Quote

#include "zcommon.acs"

script 1 (void)

{
    delay (35);
    SetFont ("Secondfont");
    SetHudSize (640,480,0);
    
    HudMessageBold (s:"AAABBB";
        HUDMSG_PLAIN,5,CR_UNTRANSLATED,320,240,10);
    
    delay(35*3);
    Exit_Normal(0);
}

Still, even after putting ACS file in the wad, it doesn't work at all, despite I followed the tutorial as written. The game doesn't execute the ACS, after I exit the level, and shows the other text message, which was defined with dehacked. Keep in mind that I have zero experience with writing ACS, so there must be something that I've been missing. If there's much better way to use alternative font for intermission text screen, please let me know. :(
