atra rātrijanmanīṣṭakālayoge viśeṣa uktas tājikālaṃkāre |Such instances are very numerous. There is also the following, where 'particular method' might fit better than 'special rule':
atra viśeṣa ukto dīpikāyām |
anyo ’pi viśeṣas tatraiva |
atha dhanarṇe lagnānayane viśeṣaḥ |
atrāntakaraṇe viśeṣa uktaḥ paddhatau |

Could you cite a few occurrences with at least the whole sentence as a context? If the form is as one sees in vṛkṣa-viśeṣa, niyama-viśeṣa (or vṛkṣāṇāṁ viśeṣaḥ, niyamānāṁ viśeṣaḥ etc., then viśeṣa has not been used in any unusual sense.

Balabhadra in his astrological work Hāyanaratna repeatedly makes use of the noun viśeṣa in a sense which seems from the context to mean something like ‘special rule' or 'particular consideration'. I haven't found this precise meaning in any dictionary and am curious to know if the term occurs with this technical meaning in any other śāstras.
