Well, "current" is meaningless, so "current task" would have to be the name
of some application property (that is, defined by the application as a
property of the application object) that has a name property. Compare:

tell app "iTunes" to get name of current track

which is

core\getd{
----:obj {
form:'prop',
want:'prop',
seld:'pnam',
from:obj {
form:'prop',
want:'prop',
seld:'pTrk',
from:'null'()
}
}
}

(See my book for more on how to read an Apple event in this format.)

But "every" is an element specifier (see my book for the technical details
on what that means). So:

tell app "iTunes" to get every track

is:

core\getd{
----:obj {
form:'indx',
want:'cTrk',
seld:abso($616C6C20$),
from:'null'()
}
}

The "set foo to" is irrelevant, since that is done by AppleScript, not by
the target app. m.
