Each of the characters has a score multiplier that will affect one of the game's three main ways of scoring - Distance Run, Enemies Destroyed, and Combos Scored. When you complete a run all the multipliers of the characters in your team (whether you used them or not) are added together. Upgrading your characters will increase the amount of points their multipliers can score by 10% so when putting together a team select a lineup that best suits your playing style so can take advantage of your characters multipliers. Knuckles and Amy multiply your enemies destroyed score, Sonic and Tails multiply your distance run score, and Sticks will multiply your combo score.
