Score some points for Labor Secretary Ray Donovan. He accepted invitations from the International Longshoremen's Association and two groups of New York area construction workers to join them at the AFL-CIO's midwinter Executive Council meeting in Bal Harbour, Fla. Generally, he failed to thaw icy relations with AFL-CIO and most of its unions. One labor official said Donovan had ''worked only the wayout fringes'' of those outside the council meetings. He added, ''I don't think he improved on it by coming here.'' But Donovan did speak with some union leaders - fringe or not.

Donovan told them the economy is recovering, that unemployment will drop to below 10 percent (it is now 10.4 percent) and that ''1984 will be a boom year.''m
