In your script I notice a double && which should be just ambersand. Further, the test should now read [ $? -eq 0 ] instead of [ $? -ne 0 ] and then it will launch the player I think.
If then still Quicktime launches before the conversion is finished I suggest you have a look at /Applications/Compressor.app/Contents/MacOS/./Compressor, which I suspect is a script in itself that may be launching the actual program in the background without waiting for it to finish. Perhaps you could then use wait loop until the creation of the file is finished (wait for a feature of the new file to change, e.g. test for non-zero length, maybe?)

FLOCK(1) BSD General Commands Manual FLOCK(1)
NAME
flock -- Provide locking API for shell scripts
SYNOPSIS
flock [-dnosvx] [-w timeout] lockfile|lockdir [-c command] | [command ...]
flock [-dnsuvx] [-w timeout] lockfd
DESCRIPTION
The flock utility provides flock(2) access to the command line or scripts. The first form locks a file or directory while the command pro-
vided is executed. If the file or directory does not exist, then a file is created.
The second form can use an arbitrary file descriptor that is provided from a shell script for example:
(
flock -s 100
# commands to be executed under the lock
) 100> /path/to/lockfile
The following options are available:
-c command Pass a command to a the shell.
-d, --debug Provide debugging output.
-n, --nb, --nonblock
Don't block and fail immediately if the lock could not be obtained.
-o, --close Close the file before executing the command. This is useful if the child forks and should not be holding the lock.
-s, --shared Obtain a shared lock.
-u, --unlock Unlock an existing lock. This is available only for a file descriptor.
-v, --verbose On error print an explanation of the failure.
-w, --wait, --timeout seconds
Fail if the lock could not be obtained after seconds.
-x, --exclusive Obtain an exclusive lock.
EXIT STATUS
The flock utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
shlock(1), flock(2)
HISTORY
An flock utility appeared in NetBSD 6.1.
