There are only a small number of colleges that actually require you to submit “all test scores.” See discussion of issue here http://talk.qa.collegeconfidential.com/sat-act-tests-test-preparation/1912440-must-you-submit-all-sat-act-or-sat-subject-test-scores-p1.html. And there are only two left that require you to submit both all SATs and all ACTs, Stanford and Georgetown The other all scores colleges give you the choice to either submit all SATs or instead ACTs .In essence, unless your daughter is applying to Stanford or Georgetown, you do not need to submit both.
In any event, colleges uniformily claim that when you submit both SAT and ACT, they will use to determine admission the test they consider to be the higher, and thus you do not have any real downside to submitting both SAT and ACT.
Based on the information provided, I cannot provide any opinion about whether your daughter should take the SAT or instead the ACT again, or even whether she needs to take another test. However, in deciding the issue she should not be concerned about submitting multiple test scores to a college.
