Not sure if i understand your query, but you can try:
select '+IsGlobalWinner', 'True',
(select top 1 TranslationText from View_CMS_ResourceString_Joined where stringkey = 'Design Awards Global Winner' and culturecode = 'en-ca')
from ...
You might as well try to return {$stringKey$}
to see if cms resolve it, i.e:
select '+IsGlobalWinner', 'True', '{$stringKey$}'
from ...
