opening a .command script simply opens a Terminal window and then 
executes the script text; it doesn't carry any directory 
assumptions with it, so it simply runs in the default directory 
for Terminal

one workaround i can think of is to wrap the shell script in an 
AppleScript saved as an applet; the applet can find the path to 
itself like this:

   set pwd to POSIX path of (path to me as string)

and pass it to the shell script like so:

   do shell script "~/script/myscript " & pwd
