Minecraft command block teleport with Target selector arguments

Question

I have a 1 tick clock, which leads to a command block with the command:

testfor @p[-262,3,113,1] {SelectedItem:{id:minecraft:stick}}

That works. It finds me under the right conditions.

Then I have a redstone comparator, leading to a redstone repeater (seemed to be needed), then another command block for the actual command to do.

If the (second) command is

tp @p -268 3 113

then it works.

If it is any of the following then it won't teleport (though the first command block is finding me)

tp @p[-262,3,113,1] -268 3 113
tp @p[x=-262,y=3,z=113,r=1] -268 3 113
tp @p[-262,3,113,1] {SelectedItem:{id:minecraft:stick}} -268 3 113
tp @p[x=-262,y=3,z=113,r=1] {SelectedItem:{id:minecraft:stick}} -268 3 113

Can anyone suggest an answer?

Edit:

I'm on Minecraft 1.8.8.

Here's the clock (off to the right is a switch to turn it on and off, off to the left is the command block circuit).

Here's the main circuit. The right hand command block is the first (the testfor). Behind it is a redstone repeater.

The left hand command block is the second (the tp).

Hope that helps.

Answer 1

Comparator and fast clocks don't mix well so here is a complete clock only solution.

Setup:

/scoreboard objectives add Selector dummy
/scoreboard objectives add Marker dummy
/summon ArmorStand -262 3 113 {Silent:1,CustomName:"Tracker",Invulnerable:1,Invisible:1,Marker:1,NoGravity:1}

Clock:

/scoreboard players set @a Selector 0
/scoreboard players set @a[x=-262,y=3,z=113,r=1] Selector 1 {Inventory:{id:minecraft:stick}}
/scoreboard players set @e Marker 0
/scoreboard players set @e[type=ArmorStand] Marker 1 {Silent:1,CustomName:"Tracker",Invulnerable:1,Invisible:1,Marker:1,NoGravity:1}
/execute @e[type=ArmorStand,score_Marker_min=1] ~ ~ ~ tp @p[r=1] -268 3 113
