When using the new execute syntax, the if score condition does not allow for either score in a comparison (> or <) to have multiple entities selected. This is not coherant with Java Edition, but limits players creativity and therefore quality of their maps/creations.

Steps to reproduce:

1. Open a world with commands enabled
2. Run command /scoreboard objectives add somescoreboard dummy
3. Run command /summon pig
4. Run command /summon pig
5. Run command +/summon cow
   +
6. Run command +/scoreboard players add @e[type=!player] somescoreboard 1
   +
7. Run command /scoreboard players add @e[type=pig] somescoreboard 50
8. Run either command:
   • /execute as @s if score @e[type=pig] somescoreboard > @e[type=cow] somescoreboard run say The pigs beats the cow!
   • execute as @s if score @e[type=cow] somescoreboard < @e[type=pig] somescoreboard run say The pigs beats the cow!

Observation:

A syntax error is given:

+Only one entity is allowed, but the provided selector allows more than one
+

Expected result:

The message "The pigs beats the cow!" should display in chat since all of the selectors in @e[type=pig] have a value greater than the single cow's value.

Why is this important?
This specific execute condition is extremely useful in determining which entity/player has the highest value, for example, a score in a minigame map. Without this condition working as proposed, players find it hard to determine which entity/player has the highest score.
