Have you tried plpgsql's SELECT INTO ?

FWIW this works for me:
alvh=> create function a() returns text as 'select ''foo''::text' language sql;
CREATE FUNCTION

alvh=> create or replace function b() returns text as 'declare b text; begin select into b a(); return b; end;'
languageplpgsql; 
CREATE FUNCTION

alvh=> select b();
  b
-----
 foo
(1 registro)

alvh=> create or replace function b() returns text as 'declare b text; begin b := a(); return b; end;' language
plpgsql;
CREATE FUNCTION
alvh=> select b();
  b
-----
 foo
(1 registro)
