Maybe they changed it recently but if I look in the 15.05 code I see the following:

this.combo++; if (this.combo >= 1 && this.combo <= 5) {base.score += 250;} else if (this.combo >= 6 && this.combo <= 10) {base.score += 375;} else if (this.combo >= 11 && this.combo <= 18) {base.score += 500;} else if (this.combo >= 19 && this.combo <= 20) {base.score += 1000;} else if (this.combo >= 21 && this.combo <= 23) {base.score += 1250;} else {base.score += 1500;}

Note that combo check starts at 1 because it adds the combo first then adds score based on the combos. Madhead is double points like Blueeighthnote
