I have previously discussed the use of pieces in Brunei (here), particularly whether it is influenced by the occurrence of measure words such as buah in Malay and 个 in Chinese (here).
Here is an extract from an article in the Brunei Times of 27 March 2011, discussing the use of plastic bags in Brunei shops. Note the use of pieces even though bags is a count noun.
In Standard English, pieces is used to let one count noncount nouns, such as information, advice, and furniture (e.g 'three pieces of information', 'two pieces of advice', ...).
However, in many New Varieties of English such as that of Brunei, pieces can be used with any noun, including count nouns such as bags and apples.
