I am not a seasoned test guru nor do I have the experience and insight of many of the parents here, but I am speaking as a young 24-year old girl with a severe LD herself (Verbal IQ 135, Performance IQ 73)who struggled but compensated in school with her superior verbal intellectual abilities.
I also think that scores at almost 5 years old should be taken with caution. Kids develop at different rates and she may still considerably improve her nonverbal abilities as she matures. Also, especially if one side is so strong, she may in time use her superior abstract, logical reasoning to find strategies to solve whole-to-part reasoning problems(which is basically what Block Design is). She might do it the long-winded, not the most efficient way, but what I am saying is that one can compensate with strengths for their weaknesses. They would never be great in areas of weakness, but they may become adequate.
I also agree with others, that another reason WISC IV might be a good test for her to take, is that it has additional subtests that WPSI lacks (or makes supplementary) such as Similarities, Digit Span, Letter-Number Sequencing (and maybe some others)so you would get more information.
While she may not have clear-cut GT needs that globally gifted kids have (and in the long run for her life it won't matter if she was in strictly speaking GT class in elementary or secondary school) , she is clearly very bright without real weaknesses (her lowest scores are still average) and as such may lead a very successful, accomplished life.
Sorry if I rambled. These are just all my thoughts related to these scores.
