Indeed, the sleep() function does not accept as argument a variable - if 
you are interested in this, open a feature request on the project tracker:

I know it is an ugly hack, but you might make it work using a while 
statement:
    instead of  :
    
           sleep ("$var(a)");
   
    do:
           $var(i) = 0;
            while($var(i) < $var(a)) {
                  sleep(1);
                 $var(i) = $var(i) + 1;
           }
