This is Yet Another Parser Subtlety (doesn't look like a bug, offhand).
There are a couple of easy ways to work around:

 - put just the ID into the variable. You would use

    put the short ID of this card into bar
    -- do some stuff
    put field "foo" of card ID bar

 - use the ever-useful "do":

    put "card id 1234" into bar
    do "put field" && quote & "foo" & quote && "of" && bar
