Hello,
I'm not sure but why 'OrganicInternet_SimpleConfigurableProducts_Catalog_Model_Resource_Eav_Mysql4_Product_Indexer_Price_Configurable'
has
'max_price' => new Zend_Db_Expr('MAX(inner.max_price)'),
but not
'min_price' => new Zend_Db_Expr('MIN(inner.min_price)'),
I had issue with minimal price on product listing but not on product view.
The table 'catalog_product_index_price"."min_price" was wrong before I added
=> new Zend_Db_Expr('MIN(inner.min_price)'),
on line 127
