I have long regexp with two complicated subpatters inside. How i can match that subpatterns in any order?

Simplified example:

/(apple)?\s?(banana)?\s?(orange)?\s?(kiwi)?/

and i want to match both of

apple banana orange kiwi
apple orange banana kiwi

It is very simplified example. In my case banana and orange is long complicated subpatterns and i don't want to do something like

/(apple)?\s?((banana)?\s?(orange)?|(orange)?\s?(banana)?)\s?(kiwi)?/

Is it possible to group subpatterns like chars in character class?

UPD Real data as requested:

14:24 26,37 Mb
108.53 01:19:02 06.07
24.39 19:39
46:00

my strings much longer, but it is significant part. Here you can see two lines what i need to match. First has two values: length (14 min 24 sec) and size 26.37 Mb. Second one has three values but in different order: size 108.53 Mb, length 01 h 19 m 02 s and date June, 07 Third one has two size and length Fourth has only length There are couple more variations and i need to parse all values.

I have a regexp that pretty close except i can't figure out how to match patterns in different order without writing it twice.

 (?<size>\d{1,3}\[.,]\d{1,2}\s+(?:Mb)?)?\s?
 (?<length>(?:(?:01:)?\d{1,2}:\d{2}))?\s*
 (?<date>\d{2}\.\d{2}))?

NOTE: that is only part of big regexp that forks fine already.
