新版execute怎么用这个计分板

Proj***

①execute @p[scores={a=..99},r=5] ~~~ title @p title §l§c数值不够！ ②execute @p[scores={a=100..},r=5] ~~~ scoreboard players remove @s a 100
新版Minecraft BE的execute指令可惜不会，上面两个指令怎么才能在新版实现？

嗷呜***

execute as @p[scores={a=..99},r=5] at @s run  title @p title §l§c数值不够！
execute as @p[scores={a=100..},r=5] st @s run scoreboard players remove @s a 100
