Well... Just paste those functions into your text konsole, and compare to my 
results:

:1() { x1=0; x2=0; x3=0; x4=7
echo $[$x1$x2$x3$x4]
}
The result is 7.

And run this code:
:2() { x1=0; x2=0; x3=0; x4=8
echo $[$x1$x2$x3$x4]
}
It crashes with message:
bash: 0008: value too great for base (error token is "0008").

:3() { x1=0; x2=0; x3=0; x4=8
echo $[$x4$x2$x3$x1]
}
works well, printing 8000.

Similar codes
:4() { x1=0; x2=0; x3=0; x4=8
s=$x1$x2$x3$x4
echo $[$s]
}
or
:5() { x1=0; x2=0; x3=0; x4=8
s=$x1$x2$x3$x4
echo $[s]
}
goes the same way like :2
Oh, if x4=9 it goes the same way as if x4=8. I didn't check higher values.
