Wait does not return the status of task1. If you need the status you will have to specify the pid of the task1.

You can't get the exit status of the background command unless you call wait to wait for it to finish. The exit code from wait is the exit code of the background task, so if you check wait's exit code that'll be the value you want.

task1 &
task2

wait    
echo $?
