You seem to be wrong...
here is a breakdown:

Hobbits - 1
Men - 2
Elves - 3
Dwarves - 3
Eagles - 4
Wizards - 10


Orcs - 1
Men - 2
Wargs - 2
Goblins - 2
Uruk Hai - 3
Trolls - 5
Wizards - 10

The Test case:

           Good             Evil
team:  [0 0 0 1 0 0 ]   [0 0 0 0 1 0 0 ]
worth: [1 2 3 3 4 10]   [1 2 2 2 3 5 10]
             3        -        3
             0        =        0

It is deffinitely a tie...

function goodVsEvil(good, evil) {
    let good_size = good.split(' ').reduce((a, b) => a + (Number(b)), 0);
    let evil_size = evil.split(' ').reduce((a, b) => a + (Number(b)), 0);

    if(good_size > evil_size){
        return "Battle Result: Good triumphs over Evil";
    }else if(good_size < evil_size){
        return "Battle Result: Evil eradicates all trace of Good";
    } else if(good_size === evil_size) {
        return "Battle Result: No victor on this battle field";
    }
}

Please take a look. I think it should pass. but I got 'Should be tie' as error. Am I wrong?
