Convert data type not applying to tax

My goal is to have commerce calculate the tax and always round up to the penny.

I'm trying to use "Convert data type" in my conditional state tax rule. The taxes are still calculated and applied as though no rounding has occurred. I've tried a few variations on this with the same results.

{ "commerce_tax_rate_ca_sales_tax" : {
"LABEL" : "Calculate CA Sales Tax",
"PLUGIN" : "rule",
"REQUIRES" : [ "commerce_order", "rules", "commerce_tax" ],
"USES VARIABLES" : { "commerce_line_item" : { "label" : "Line item", "type" : "commerce_line_item" } },
"IF" : [
{ "commerce_order_compare_address" : {
"commerce_order" : [ "commerce-line-item:order" ],
"address_field" : "commerce_customer_shipping|commerce_customer_address",
"address_component" : "administrative_area",
"value" : "CA"
}
},
{ "entity_has_field" : { "entity" : [ "commerce-line-item" ], "field" : "commerce_product" } },
{ "entity_has_field" : {
"entity" : [ "commerce-line-item:commerce-product" ],
"field" : "field_taxable"
}
},
{ "data_is" : {
"data" : [ "commerce-line-item:commerce-product:field-taxable" ],
"value" : 1
}
}
],
"DO" : [
{ "commerce_tax_rate_apply" : {
"USING" : {
"commerce_line_item" : [ "commerce-line-item" ],
"tax_rate_name" : "ca_sales_tax"
},
"PROVIDE" : { "applied_tax" : { "applied_tax" : "Applied tax" } }
}
},
{ "data_convert" : {
"USING" : {
"type" : "integer",
"value" : [ "applied-tax:amount" ],
"rounding_behavior" : "up"
},
"PROVIDE" : { "conversion_result" : { "conversion_result" : "Conversion result" } }
}
}
]
}
}
