How can I give points when someone is standing near an item using Minecraft commands?

/execute as @a store success successscore to 1* run clear @s *youritem*  
/*add point too* [scores={successscore=1..}]  
/*set scoreboard of [scores={successscore=1..}] back to 0  

These are not the exact commands, but you get the point

Here is just "an item":

execute @e[type=item] ~ ~ ~  scoreboard players add @p MYOBJ 1
kill @e[type=item]

Or for an item named Apple:

execute @e[type=item,name="Apple"] ~ ~ ~ scoreboard players add @p MYOBJ 1
kill @e[type=item,name="Apple"]

The first command should be in a repeating always active command block and the second in a chain always active conditional.
