I'm trying to testfor a named armor stand at a certain coordinate along the x-axis, using this command:
/testfor @e[type=ArmorStand,name=Torcher,x=248,r=2]
The command works without the radius parameter, as it should, but not with it.
The command leads into some other command blocks that aren't too relevant, but here they are anyways:

Command Block 1:
/execute @e[type=ArmorStand,name=Torcher] ~ ~ ~ /setblock ~ ~ ~ minecraft:torch

Command Block 2:
tp @e[type=ArmorStand,name=Torcher] ~-256 ~ ~5
